Immunology

The immune system involves a variety of cells and mechanisms to protect the body against pathogens. Leukocytes, including basophils, neutrophils, and monocytes, play crucial roles in inflammation and phagocytosis.

Immunology

Aff Mat

After a B cell with antigen is initially activated by at Th cell

Affinity Maturation happens in germinal center - B cell is activated by Th2, starts rapidly reproducing and mutating (regulated by Th2). The one with the highest affinity reproduces - some become plasma.

1) IgM released by B cells to make immune complexes

2) Dentric cells pick up complexes and bring to follicle to allow affinity maturation of B cells

3) If B cell has high affinity to an antigen and gets costimulation by Th2 then it starts to proliferate
