What is one of the major functions of CD8 coreceptors?
Understand the Problem
The question is asking about the specific roles of CD8 coreceptors in the immune system, particularly in relation to T cells and their functions. It presents multiple choice options to identify the correct function.
Answer
Acts as a co-stimulator for T cell activation.
The CD8 coreceptor primarily acts as a co-stimulator by increasing the sensitivity to antigens, which enhances T cell activation.
Answer for screen readers
The CD8 coreceptor primarily acts as a co-stimulator by increasing the sensitivity to antigens, which enhances T cell activation.
More Information
The CD8 coreceptor plays a crucial role in the immune system, particularly in recognizing and responding to infected or cancerous cells by interacting with MHC class I molecules.
Tips
A common mistake is confusing the roles of CD8 and CD4 coreceptors. CD8 is associated with MHC class I and cytotoxic T cell functions, while CD4 is associated with MHC class II.
