Direct and indirect activation of NK cells. The “classical” pathway of NK cell activation (A,B) results from skewing of the balance between signals transmitted via inhibitory and activating receptors. The “indirect” pathway of NK cell activation results from contact-dependent and soluble signals derived from accessory cells and T cells transmitted to activating receptors on NK cells (C).

Delayed type of hypersensitivity simplified Type IV or delayed type of hypersensitivity is a bit different because unlike type I & type II hypersensitivity which is mediated by antibodies, type IV is mediated by T cells. The whole response is directed by chemokines and cytokines released by antigen-stimulated Th1 cells.

Using gummy bears to teach genetics! This would be much faster than growing Mendel's sweet peas! Not to mention, super cute and fun! Will have to bookmark this so I can use it when we cover dominant and recessive genes!
