From what you learned in class, TI-antigens refers to highly repetitive epitopes on the surface of microorganisms that cause extensive cross-linking of B-cell receptors and co-receptors, leading to B-cell activation in individuals without a thymus.

The majority of centroblasts using the DNA- modifying enzyme activation-induced cytidine deaminase (AID) you would expect to find where in the body?

How do intestinal epithelial cells help defend mucosal tissue?

Erythrocytes have complement receptors (CR1) on their surface therefore they can bind, phagocytose and destroy pathogens coated with complement.

The B-cell co-receptor can bind to what/which complement degradation product/s?

In a helminth parasitic infection, which cytokine/s will lead to B-cells isotype switching to make IgE?

The B-cell co-receptor can bind to what/which complement degradation product/s?

Which receptor on B-cells binds CCL21 and CCL19?
