For Immunology Chapter 11 Day 3 Describe the functions of the cell surface markers CD44, CD62L, and CCR7.  Discuss the purpose behind the expression levels of these proteins in T cells: naïve, effector, central memory, and effector memory.

For Immunology Chapter 11 Day 2 What are the three features that define helper T cell subsets? Figure 11-9 is confusing. Redraw it with a separate pair of DCs and naïve T cells.  In other words, draw DC/T cell interaction for Th1 and a separate DC/T cell interaction for Th2.  Add in the relevant information … Continue reading T Cell Differentiation

For Immunology Chapter 12 Day 3 The book made an analogy between B-1 B cells and γδ T cells. In what ways are these cell types similar? To what extent do B-1 B cells and MZ B cells rely on help from T cells? What other cells do these B cell subpopulations appear to interact … Continue reading B Cell Subsets (Some Similarities with T Cell Subsets)
