Alloimmune Recogition: Direct and Indirect Pathways

Alloimmunity is driven primarile by diferences in majar histocompatibility complex (MHC), called human leucocyte antigens (HLA) in humans. The recivent 's immune systemm call donor HLA througo tmain ways:

  • Pertama, pertama, pertama, pertama, pertama, sel T; 0; 33. Arah trade:

Both pathways activate a cascade of cellular and humoral efftors, making alloimunity a central focus of immunosupsive protcols.
