Q

What do cluster of differentiation markers do? What are their roles?

A

Cluster of differentiation (CD) markers signal the presence of cell surface proteins, which leads to the identification and characterization of leukocytes.
CD markers have multiple roles:
-Cell identification
-Antigen or cytokine receptors

100
Q

What surface marker mediates homing in on colonic tissue? How?

A

Α4β7 on T lymphocytes mediate homing in on colonic tissue by binding to MAdCAM-1.

101
Q

Where do naive lymphocytes home to? Where do activate lymphocytes home to?

A

Naïve lymphocytes home in preferentially on secondary lymphoid organs such as lymph nodes, spleen, and Peyer’s patches. This ensures a maximal probability of a diverse TCR repertoire coming in contact with unique antigens. Once activated, lymphocytes enter the circulation, whereby they encounter antigen residing in different tissues to elicit a strong memory response.

Why are cell surface markers so important? How does pathogenesis occur from defects?

A

Cell surface markers play an important role in cell function and survival. Clinical disease results as a defect in expression or in function, or by opportunistic use by a pathogenic organism.
