Question
Chapter 22.4, Problem 15WDYL
Summary Introduction
To determine:
The features that distinguish the receptors of helper T- lymphocytes, cytotoxic T- lymphocytes and B-lymphocytes.
Concept introduction:
All the immune cells like the T-lymphocytes, B lymphocytes, macrophages, dendritic cells act as antigen presenting cells. The B-lymphocytes can make direct contact with antigens and the T lymphocytes require co-receptors known as CD molecules.

- What is the difference between innate immunity and adaptive immunity?arrow_forwardWhat do T cell receptors do and tell How many T cell receptors do T cells have?arrow_forwardThe immune system involves both the humoral and cell-mediated branches. It is known that T cells can perform a range of different functions once selected by antigen encounter, including secretion of soluble compounds to aid other white blood cells, such as B lymphocytes. If T cells can aid the function of B lymohocytes, then is it incorrect to say that both branches of the immune system (humoral and cell-mediated) involves B cells? I ask this question because I commonly hear that humoral immunity involves B cells rather than both branches.arrow_forward
