OVERVIEW OF THE IMMUNE SYSTEM

THE GOOD BAD AND UGLY OF THE IMMUNE SYSTEM

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Memory B and T cells help protect the body from re-infection by pathogens that infected the body in the past. Being able to resist a pathogen in this way is called immunity. Is this statement true or false.
A
True
B
False
C
Either A or B
D
None of the above
Explanation: 

Detailed explanation-1: -B cells produce antibodies, which bind to pathogens and mark them for destruction by other immune cells. T cells kill infected host cells or help B cells produce more antibodies. Memory B and T cells persist in the body for many years, providing lifelong protection against reinfection by the same pathogen.

Detailed explanation-2: -But sometimes, when the body needs a more sophisticated attack, it turns to its T-cells and B-cells. These cells are the special ops of the immune system-a line of defense that uses past behaviors and interactions to learn to recognize specific foreign threats and attack them when they reappear.

Detailed explanation-3: -B lymphocytes are the cells of the immune system that make antibodies to invading pathogens like viruses. They form memory cells that remember the same pathogen for faster antibody production in future infections.

Detailed explanation-4: -The T and B lymphocytes (T and B Cells) are involved in the acquired or antigen-specific immune response given that they are the only cells in the organism able to recognize and respond specifically to each antigenic epitope.

Detailed explanation-5: -These cells develop within germinal centers of the secondary lymphoid organs. The most important function of memory B cells is to remember the first encounter with invading pathogens, and to provide effective protection against secondary infection for years (Crotty et al., 2003).
