Include all appropriate cell types and interactions involved in your description. Assume that the antigen is a protein, which would elicit “help” from T helper cells. Be brief but as comprehensive as possible.   Question 3: Shyam Mohapatra Describe the differences between thymus (i.e. T cell) dependent and thymus (i.e. T cell) independent immune responses, including examples of the antigens for T dependent and T independent responses and the nature of the antibody responses elicited by these 2 types of antigens. Be as brief but as comprehensive as possible.
