Propaganda!

The regulatory T cells (Tregs), formerly known as suppressor T cells, are a subpopulation of T cells that modulate the immune system, maintain tolerance to self-antigens, and prevent autoimmune disease.

A phagosome is a vesicle formed around a particle engulfed by a phagocyte via phagocytosis. Phagosome formation is crucial for tissue homeostasis and both innate and adaptive host defense against pathogens.

I'm gonna post more regularly here, but please do feel free to send asks or submissions.

Humans are Space Orcs, but aliens discover living decay in humans.

"So you say, as you still live and breathe, your body starts to..."

"Decay, yes. It's why Xy has bone degeneration even though your treatments have been helpful."

"But why is that? Should your bodies not have evolved into the peak of your planet?"

"Our body is at best a scrapship from Jungari-9000 and at worst a tugboat on Nars. So many different parts, so many different functions, some brains lose the ability to keep everything up to shape at an earlier age. But it happens to everyone, the decay."

"Most fascinating."

#free radicals #humans are space orcs #humans are space oddities #humans are space fae #humans are deathworlders #humans are space australians #humans are weird #so the topic im talking about here is oxidation #and how corrode our cells by existing in our body #its just a natural thing to slowly die out as a human #but extremely not for aliens #who might not be carbon based

today im thinking about malaria in ancient rome.

about the fact that P. falciparum (the most dangerous kind of malaria) was likely endemic at least from the 2nd century BC onward that Galen said semitertian fevers (P. falciparum infections) were more common in Rome than anywhere else in the Roman Empire that the most severe manifestations of P. falciparum (quotidian fevers + cerebral malaria) were most common in babies and young children, an epidemiological observation that indicates the transmission rate of P. falciparum was extremely high in Rome that Quintus Serenus said there was no Latin word for semitertian fevers (they used a transliteration of the Greek, 'hemitritaeos') because "no one, i think, could have named it in our language and mothers would not have wanted to"

#working on my thesis gonna bring down the mood of the whole department #but i feel like i have to honor them #and the thing about malaria that fucks me up is P. falciparum has been around for tens of thousands of years #its not a disease of agriculture like smallpox or of sanitary issues that come with civilization like typhoid #it predates agriculture its been found in the bodies of mummies from ancient egypt and skeletons from ancient greece and rome #there are species-specific plasmodium parasites for gorrillas chimpanzees and humans #which to me indicates there was a plasmodium parasite for every now lost hominid #malaria is the strongest recent evolutionary pressure on the human genome #upwards of 30% of people in some parts of the world are heterozygous for sickle cell anemia #or heterozygous for SE asian ovalocytosis #thus it was more evolutionarily advantageous for 2-3% of all children to die #so about 30% of people could be protected from severe malaria #these mutations take a long time to evolve. parasites take a long time to evolve #there are people who mourned their infants tens of thousands of years ago in languages we will never know with rituals we will never see #and i cant do anything about any of that but i can keep going to the lab every day and trying my best to figure it out #because so many generations of humans stretching back to before we were human could not

Angels’ trueforms in their most memorable moments [26/?] - Nephilim fetus: regular nephil, sired by a regular angel (above) and Jack, sired by Lucifer (below)

#NEW ONE FOR THE FIRST TIME IN AGES!!! I TOLD YALL I WASN'T DONE WITH THIS!!! #SO sorry it took so long. i still can't control my artblocks. but i've had this idea for so long #spn #spnart #spn art #mine.caro #ok so. explanation time. cracking my knuckles. i haven't done this in so long ahhhh #so i HAD to do nephilim eventually. of course. and the key thing about them is they're the children of angels and humans #and i figured i'd start with a fetus bc that's the nephil version of the angel factory settings. and that needed a shape like the AFS did #it felt right to go with a sphere. and after the nephil is born and becomes a more distinct individual etc the spheres unravel in different #ways. some open up like pillbugs (woodlouse? i never know the right name). others sprout like seeds. others spiral out. the possibilities #are endless hehe. and the sphere had to have a mix of angel trueform and human soul. which i've been coding so far as the black and white #trueforms and collages. so that was settled. but that couldn't be it bc it's not just one and the other. they're integrated in one thing #so. for the regular nephil i filled out some cells in black like angel trueforms and others with collages. in the trueforms cells #and it's Earthly Things like plants and body parts and fruits and animals water and the sky and rocks etc. and a bigger solid collage block #that's just body parts. so specifically human stuff. AND THEN i took that sphere (well circle) and cut it up and kintsugi'ed it with #angel grace. feels like a way to go to represent nephil. and then i added the angel wheels to look like a sort of proto version of AFS #and that's regular nephil. for jack he had to be different bc lucifer nephil is thee antichrist. it's different. so i followed the samelogi #but based on the lucifer trueform instead of AFS. so i painted the solid black with alcohol-based markers so i could smudge it with alcohol #and then added the collage bits (more from a fitness magazine than a fashion magazine i used for the other one. gets a more aggressive vibe #i think. more flexed muscles) and painted the chaotic smoke cloud over it. and then i did the same kintsugi process. i was gonna do it in #silver but figured it made no sense. it should be the same. and the black and gold look cool #and what else. regular nephil has a rosary-like umbilical cord! emerging from one of the poles of the sphere so to speak #and jack has none :// partly bc i forgot at first kfjg but then i didn't go back to add it bc i feel that matches fetus jack's situation #considering it's an angel grace umbilical cord #and i think that's it! #these aren't up on the stores yet but im gonna add them now #hope they're worth the wait. if anyone was waiting for more #Trueforms

Sometimes I wonder why cold symptoms always get worse in the evenings there has to be a logical explanation for that

#i need to know #i might have only choosen the biology major because I had no other choice but i do genujnely think the human body is a fascinating object #we should not exist there is no reason we should exist but here we are and here we are exactly the way we are isn't that funny? #it's such a silly body too what you're telling me I could produce an entirely new person in here #but one falsely mutated cell that brances out and has a personal problem with me specifically can kill me in a year or less? #that doesn't seem right. #if you think about it children are a little bit like cancer actually #i won't be opening that can of worms actually lets keeo that locked away in zhe cupboard #oh yeah and you can inherit the murder cell mutation because of course you can #and then we came up with thousands of ways to cure thousands of ailments and what did we do we put them behind a paywall #come onnnnnn where's the fun in that #we have this cool stuff why do you not let us use the cool stuff #i don't do meds on principle if I have anything I jusz sit that out raw and painful but hey it's not my place to tell others to do it my way #i just don't like the thought of building up a resistance against stuff so I just take my ibuprofen if there really is no way to function #without them anymore #luckily that's not the case a lot of times #i can work fine with the headaches they're just annoying #make the head foggy and words take a second to comprehend and the light hurts but i can work with it #have you ever had two kinds of headache atbthe same time thazs an experience #dealing with a tensuoj headache and then also the clogged nose headache is. it sure is something #you don't know where exactly it hurts and it's not so bad that you have to lie down but then you hold your head the wrong way #and Boom a bomb goes off up there #fascinating stuff #how did I even get here

[gay-artificer]

Im heavily debating writing a full, APA style and cited paper on the rot and its relation and similarity to cancer in function, proliferation, and genetics. This would be a horrible idea for my free time. But it would be a conceptually funny piece of fanwork for rain world to have

#unironically my estimation for the size of this would be like. 5-10 pages minimum #more likely 10 with the scope of things i would want to cover #and the complications of explaining the ins and outs of weird genetic quirks cancers can have to a layman #and how that applies to the rot #like cancer as humans know it is not technically contagious since its the bodies own cells #but dogs can actually 'catch' cancer from other dogs because of a very specific mutation #along with three other types of tumors that are transmissible #how fucked up is that??? and how fucked up would it be to read a 20000 word rain world essay comparing dog tumors to a fictional spider glo

thinkin about dragon age for the first time in like ages but smth that always struck me as odd is how often cole is mischaracterized and misrepresented. like i can tell when someone hasnt read asunder from how they depict cole. dudes half avvar like hes not a tiny little boy. thin yeah but have you SEEN his LEGS?? and his SHOULDERS? this is a full grown half-avvar man. the avvar are fuckin massive like theyre chasin up the qunari regularly in terms of height. spreading my tall cole agenda

#my t #daveposting #continuing my cole is a full grown adult w/ full grown adult thoughts and wants agenda too #im gonna give him so many boyfriends #just as he deserves tbh #anyway my personal hc for cole body specs is that hes perpetually malnourished but sinewy and shockingly strong #hovering somewhere btwn 6'-6'4'' #the juxtaposition of his frame vs Who He Is vs What He Does should be eerie and weird #plus thinking abt the human cole feeling scared of growing 'too big' #catching too much attention #he wants to be small but his avvar genes doesnt let him so he slouched and was quiet and kept to himself #and then he starved to death in the white spire cell #so when the spirit found him and became him the spirit imitated how quiet he made himself to be #and in-game-cole only is able to really change his body re gaining weight/muscle after becoming fully human #we like there being a considerable gap in og human cole's life where he wanders as an apostate for a few years so he grows like a gd weed #i have a lot of feelings about cole dragon age

A fuck it I'm going in.

I need stampede plant lore/biology hc's

Flowers gained sentience from a higher dimension and had some babies but read the Bible too so now we've got some angel action. But I wanna know how they're intelligently designed cryptids.

That energy buzzing purr shit is my jam.

#honestly im just amassing a ton #i rewatched the flashback episodes and i ate up all the isms about the species #talk to me about thier super fast childhood #or thier freaking body suits that serve as a protective skin #while the make up is human theres gotta be some plant cells in those boys #gimme hc about a hypothetical culture had knives won #theyre designed to communicate #trigun #trigun stampede #slightly unrelated i think vashs wings are gonna manifest with a petal motif sinces hes not hyped up on interdimensional juice after july

"If your entire body is replaced by speedforce are you really the same person you started out as? "

i mean seeing as how skin cells work in the real world I gotta go with "obviously"

I gotta tell ya, if your brain completely dies and then rebuilds itself from scratch then you might wanna go see a doctor. Same for any nerve cell, really.

Cause yeah, skin cells do replace themselves at a very quick rate but your brain? You're stuck with what you got. And, uh, it's arguably the most important part. It's what makes you 'you'.

#you get a set stock of neural precursor cells and your brain builds itself throughout adolescence #once you are out of precursor cells thats it. you get one brain. no take backs #so yeah the Ship of Theseus doesn't really apply to the traditional human body cause your brain definitely doesn't replace itself #youve got major fucking issues if it does. like it'll rework some pathways here and there but hooooo boy that stuff is pretty important #you do not want the brain going offline for renovations #also technically bones don't either. though thats weirder cause they can make new bone growth but you aren't ever losing the old bone cells #cept teeth #and the bones that fuse together #so yeah nerves and bones. you're kinda stuck with them #also high-key pretty sure the heart as well but im too tired to double check that #and gametes in AFAB peeps #so ye. the question very much does still stand. if your entire fucking body gets obliterated and rebuilt. are. you. still. you?

Oedon does have a form, technically

Thinking about how both of Oedon's runes are associated with the bullets that are created from the blood, that also works with how Frenzy turns one's blood into spears (so, cold weapon). Well, not just Frenzy, but seems like crystallising blood into weapon is the process that is already touching everyone more or less:

Oedon is basically some gremlin dwelling within the blood of mortals itself, urging the hunt and bloodspill even more than human nature already suggests, so, honestly, as soon as humanity contacted the Great Ones again it is hard to blame people that so many of them give into their own impulses - and see making their blood 'grey', or 'pale' as the salvation (since cosmic Kin do lose their blood color). Needless to mention that Frenzy is calmed down by consuming Sedatives which are blood-based.

It is just somewhat ironic that celestial emissaries, Ebrietas and celestial larvae are all associated with the 'Moon' ( x ). 'Moon' is the very thing that guides the hunt and gives hunters the power, but I guess people like Laurence or Gehrman still consider it a blessing because it gives them power to kill the beasts (again, the hypocrisy of which only like, Djura and Suspicious Beggar realised). Like... maybe it is not all that bad if you are on the "privileged" side of the twisted system (so the hunter, or the blessed kinnie taken under that Great One's wing)? Though naturally I think 98% of people in the setting do not realise it because we live in a society I guess

But again, I did have the idea that Oedon must be Flora's baby, somehow killed and maybe consumed too even before it was born (she has missing guts like if someone ripped her entrails and is implied to have lost her child). And just lives as a 'spirit' trying to reconnect with her by urging the cycle of the hunt further, but yeah it is only today when I realised how painfully self-explanatory the connection between Frenzy and bullets both being weaponized blood is.

#bloodborne #bloodborne theory #bloodborne observation #formless oedon #i do not know what it makes out of oedon impregnating arianna (and most likely fauxsefka too) really #other than they probably grew and matured within humanity past the 'child' role #basically normal human child is egg cell + sperm cell #but celestial larva is egg cell + WTF #i also made a point once that the note in oedon chapel refers to oedon #localisation made it 'spider hides our lost master from us' but in original it is 'hides our invisible lord from us' #basically rom said 'your body your choice' and oedon disagreed and no one talks about that!

If I had a nickel for every time Mihoyo made a storyline about breaking a population out of a collective dream/consciousness, I’d have at least 4 nickels- which isn’t a lot, but Mihoyo what the fuck

#honkai impact #genshin impact #actually no- 4 is starting to be a lot #what’s with Mihoyo’s vendetta against hive minds??? #and why’s every scientist trying to advance human evolution in a Mihoyo product some puppy torturing lunatic #I genuinely find it really weird that they try and make it seem like advancing human evolution and unethical practices are somehow tied #like I’m sorry- I thought the problem with Mobius was that she disregards safety and doesn’t care that most of her experiments are lethal #not that she made a super soldier serum #I thought the problem with Dottores was that he kidnapped and tortured children #the cloning himself thing is cool #I don’t give a shit about what he does with his own body #it’s just kinda weird to me that Mihoyo seems to take the stance that altering the body medically is a sin against nature #though now that I’m thinking about it I’m pretty sure I remember their being a religion from China where your body is a gift from your #parents and altering it at all is seen as disgracing them #including cutting your own hair #but considering the amount of characters in Genshin with cut hair and piercings I don’t think that really applies here #I really wish Mihoyo would actually bother to explore genetic alteration in a non-axe murders setting #like stem cell research and agriculture #cuz it’s not inherently bad

Propaganda!

The endoplasmic reticulum (ER) is, in essence, the transportation system of the eukaryotic cell, and has many other important functions such as protein folding. It is a type of organelle made up of two subunits – rough endoplasmic reticulum (RER), and smooth endoplasmic reticulum (SER). The endoplasmic reticulum is found in most eukaryotic cells and forms an interconnected network of flattened, membrane-enclosed sacs known as cisternae (in the RER), and tubular structures in the SER. The membranes of the ER are continuous with the outer nuclear membrane. The endoplasmic reticulum is not found in red blood cells, or spermatozoa.

A membrane transport protein (or simply transporter) is a membrane protein involved in the movement of ions, small molecules, and macromolecules, such as another protein, across a biological membrane. Transport proteins are integral transmembrane proteins; that is they exist permanently within and span the membrane across which they transport substances. The proteins may assist in the movement of substances by facilitated diffusion or active transport. The two main types of proteins involved in such transport are broadly categorized as either channels or carriers.

There are a surprising number of videogames in which there is a deliberate, painstakingly programmed choice for you to fuck a lovely eldritch squid creature and I just appreciate that about the medium.

#fallen london #like squid specifically #is it because it's a slightly warped mirror of our humanity #sounds a bit anthropocentric #more the reminder that intelligence in the way humans frame it #is not exclusive to our species #or even our closest common ancestors #cells and nerves and bodies can be wired for all the same features we have #even better ones! #that look nothing like our blueprints #and you know what #sometimes we want to put our tragically sapien dicks in that #but the question becomes #do eldritch squid creatures desire to put their spermatangia in us? #are they having the same feelings? #I should hope so or at least that these squid creatures are enjoying themselves

human!dagger rewrite of Hunting Lessons is officially complete letsgo. technically i did it last night but i wanted to proofread today once i had ykno. slept. which is a good thing bc i actually found a couple details i missed. only one part of a scene had to have substantial changes made to them but even then it's just flipping some of the dialogue and character actions. 99% of the original plot is still intact ^-^

#Little Dagger AU #i'll post the adjusted version ! eventually !!! #since the plot changes are negligible I'll just edit the original ao3 post and put a comment in the summary and/or author's notes #now i am free to work on Prime Meridian in peace without being haunted by inconsistencies w Hunting Lessons yippee #also! this allows me to properly declare Miss Me? as part of the series #bc dagger and MissMe!cell are the same person from the same au!!! #i just didnt officially connect them b4 bc dagger was cat hybrid and MissMe!cell was “human” (cat hybrid w features hidden under clothes- #-or augmented to be hidden somehow so they didnt affect the plot or MM!cell's body language in any way) #anyway back to the hw grind ive got some Shit i need to handle before the floodgates open today

Fun fact about me is that I'm taking a headcanon I came up with for Sephiroth and recontextualizing it for Wolfwood, so

One hand strayed up to his hairline. He used to have a scar there, where one kid had beamed him right in the head with a good-sized chunk of stone. It had never been an especially big scar, but the regeneration the Eye had forced on him had worn it down to nothing. Just like the scrapes on his knees, the chunk of his left elbow that he’d taken out after falling off the roof, the slight pale mark on his right cheekbone…even that one he regretted losing. The only marks he had left on him were the callouses on his fingers and shoulder from the Punisher, and that was because he was carrying it around so much that the chemicals couldn’t keep up. Constant wear and tear.

there is that.

#it's about forced alienation from your body #it doesn't belong to you anymore. it can't even carry the history of your hurts--big or small #it's a blank slate for someone else to impose their will on #shinra or the eye same difference #the way I was thinking for Sephiroth is that he's literally never had a scar once in his life #it's just another way he's not like other people not quite human. a sign he's being lied to #he just doesn't know about what #now for Wolfwood the only thing he's ''allowed'' to keep are the things that mark his servitude #every other bit of his history gets erased as his cells regenerate #big hurts (hinting at integrating his anime backstory here) #small hurts (childhood injuries proof that he was once just a normal kid) #it's all chipped away bit by bit #definitely exploring this concept more later #anyways I love pain and hurting #fic blogging

anyway our CNS & brains are pretty complex, like we've barely figured out getting people with partial spinal cord damage back driving their own bodies + when we do it's still a roll of the dice & the processes are not all well understood... encephalitis can caused locked-in-ness like with sleeping sicknesses, akinetic mutism, etc where the body itself is not physically incapable of movement & action, but nothing is out there that jumps in and takes over from a driver who's paralyzed or asleep at the wheel... that's not actually a thing, it's fun speculative fiction but not representative of reality— so really, no worries lol

#the other thing is... we're megafauna? #like cordyceps hitches a ride on hymenoptera to get from point A to point B as part of their life cycle. no conscious goal #bc people often say ''oh a fungus/virus/microbe WANTS to spread & reproduce'' it doesn't WANT shit. #it is a single cell organism & s/t not even that— viruses are weird & not even always technically alive UNTIL a host or vector is infected #but my point being... we're like ''gone girl''... #amy dunne saying ''you think you'd be happy with piggybacking on my body on the way to something else? no way baby! I'm it.'' #microbes don't NEED to do all that highly specialized evolution to take over my legs like that & walk over to a tree. #cordyceps needs more than one ant. nothing needs more than a potential for human to human transmission x 8 billion. #and you don't need my brain or body control to do that when you have my blood my spit my lungs etc #path of least resistance + greatest effectiveness; a zombie virus doesn't need to evolve. we have aids we have rabies we have sars #give us scurvy and it's curtains lol... we don't need viral zombies if a new strain of polio makes a comeback. #we're the tripods in war of the worlds and it's our own planet that can kill us with a cold. #but it's more fun to catastrophize about a Big Scary Fantasy Germ than to be like ''get a DPT vaccine.'' #it won't be zombies; it will be infinitely more mundane; it will be infinitely worse.
