PATHOLOGY- ADAPTIVE

Question 1

What is adaptive immunity?

Answer 1

It consists of cell-mediated responses and antibody (humeral responses). CARRIED OUT BY B AND T cells.

Question 2

What do T cells do?

Answer 2

T cells drive cell-mediated immunity, it involves the activation of macrophages, natural killer cells (NK) and antigen-specific cytotoxic T- lymphocytes. A key feature of the adaptive immune system is immunological memory, whereby each pathogen is “remembered” by a signature T cell receptor, and/or B cell receptor.

Question 3

What do B cells do?

Answer 3

B Cells produce antibodies and drive humoral immunity. A key feature of the adaptive immune system is immunological memory, whereby each pathogen is “remembered” by a signature T cell receptor, and/or B cell receptor.

Question 4

What three main molecules are involved in the recognition of foreign antigens?

Answer 4

• Toll-like receptors (Innate).
• B cell receptors (Adaptive).
• Major Histocompatibility complex (MHC).

Question 5

What does a B cell receptor do?

Answer 5

Multiple genes come together to make things such as mhc proteins and t and b cell receptor. It can pick and choose what genes it wants- wide rnge- diff specific patterns for specificity.
