What happens after pathogens gain entry into the body?

Antibody-dependent cell-mediated cytotoxicity (ADCC) is an important effector mechanism in immunity to virus infections. Which of the following cells is implicated?

IL-4 production by T cells lead to the induction of which isotypes?

 The germinal center is a region within the secondary B-cell follicle where sustained B-cell proliferation and differentiation take place. Periodic interactions between the B cells and TFH cells can occur

An effective adaptive immune response prevents reinfection. This protection is an absolute response against all pathogens.

The body’s ability to traffic T cells to a particular tissue is achieved in part through the expression of adhesion molecules (homing receptors). T cells that home to the skin would express which of the following?

Which of the following depicts the steps of B cell activation in the correct order?

While innate immune responses to all types of infections induce local inflammatory responses due to activation of blood vessel endothelial cells, some components of the innate response differ depending on the nature of the pathogen. In the case of intracellular bacterial, dendritic cells and macrophages produce a cytokine that stimulates ILC cells to produce:

Interleukin 2 (IL2) is a cytokine that

Naïve T cells require the following for survival
