Homework Answers
11. Expressing multiple MHC molecules is beneficial to a single individual as this increases the likelihood of an effective immune response to a specific antigen. The MHC molecules process the antigens and present them to the T cells. Thus it is difficult for the pathogens to evade immune response.
12. Effector B cells include antibody secreting B cells. These are known as plasma cells.

1)You inject a mouse with a protein antigen X. This is the first time the mouse has been exposed to X. In the course of clearing X from their body the mouse will launch an immune response to antigen X. Over the course of the immune response antigen X will encounter naïve, effector and memory lymphocytes (B- and T-cells). There are distinct differences between the function and role of each type (naïve, effector and memory).Differentiate between naïve, effector and memory lymphocytes. Focus...
