PHGY 209 Lecture Notes - Lymph Node, Dendritic Cell, T Helper 17 Cell
Document Summary
Anti-cell receptors are anti-self, only 5% cells leave thymus/marrow because 95% are cyto-toxic. Cd4+ helper cells are pro-inflammatory and are polar to th17 bowel can distinguish between foreign and dangerous and those that are not. Maintain suppression of materials that are foreign and not dangerous follicular b are in the lymph node and help in immune system. Viruses don"t live in dendrites, only inside cells where they take over cellular processes. Genome taken over by virus, which in turn, makes more viruses. Dentritic cell digests virus like it is a bacteria. Th1 helper cell (cellular) has t-cell receptor specific for peptide. Tcd8+ cell interferon, inf (for inflammation) cause maturation and proliferation of c cell. Bring in infected cell (liver in this case), have erythrocytes, which has mhc class 1 molecules (all cells have this) Liver cells don"t digest well, virus has taken over liver cell and is making viral protein and taken up by.
