VACCINATE YA KIDS FFS

your bulldog isn’t being quirky it’s actively trying not to die every 10 seconds

not to be positive on main but sometimes things really are ok. sometimes you really will be happy and safe and warm. sometimes you really will be giggly and blushy and full of love. sometimes the night is chilly and your home is cozy and your tea is perfectly steeped and your phone lights up with a message from someone you love. sometimes life really is quite lovely.

Metastatic embolus from breast adenocarcinoma in the lungs

cancer cells are usually very metamorphic, which you can tell by the different shapes of the nuclei in this embolus. i love how you can see the metastasis inside a vessel perfectly in this picture!

Your body deserves to feel safe. Your soul deserves to feel safe. I hope you find environments and invest in healing steps to accomplish this, because you and your body are good and deserving.

Antibodies are the secreted form of B-lymphocyte receptors and are a part of adaptive immunity, but how are these proteins formed?

Above is a diagram illustrating Paul Ehlrich’s Side Chain Theory of Antibody Formation. Ehlrich proposed that immunoglobulin molecules, a fundamental component of adaptive immunity, served as membrane bound proteins that bound to particular threats, similarly to the former “key in lock” view of enzymes in catalyzing biological reactions. Ehrlich also suggested that the action of binding a pathogenic molecule to the receptor would generate a signal to stimulate the production of more receptors of the same specificity. These “side chains” that were added on would then break off from the cell surface and become what we call antibodies.

 We now know, however, that soluble immunoglobulin receptors are specially manufactured to be secreted as antibody, rather than just “breaking off” of the lymphocyte, even though they have the same specificity as their membrane-bound counterparts.
