Effector memory cells (TEM), are recirculating cells that can readily enter tissues at sites of inflammation and are ready to rapidly respond to re-infection. The subset of TEM cells provides an important component of protective immunity to re-infection by the same pathogen because:

Which of the following is a characteristic of mature plasma cells?

Antibody Dependent Cell Mediated Cytotoxicity (ADCC) is

Which of the followoing isotypes can cross the placenta?

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:

What is the role of the FcRn receptor?

 IgA is produced in copious amounts, estimated to be a rate of 3 g/day. Nearly all of the IgA secreting plasma cells are found in the gastrointestinal tract where the secreted IgA is transported across the intestinal epithelium with the help of:
