Which of the following cells is responsible for the production of antibodies in response to infection or vaccination?

A.

T cells

B.

Natural killer cells

C.

B cells

D.

Macrophages

Answer and Explanation

The Correct Answer is C

Explanation: B cells are a type of lymphocyte that plays a central role in the adaptive immune response. When activated by the presence of specific antigens, B cells differentiate into plasma cells, which are responsible for producing large quantities of antibodies that can target and neutralize the invading pathogen.

Incorrect choices:

a. T cells are another type of lymphocyte that is involved in cell-mediated immunity, where they directly attack infected or abnormal cells. They do not produce antibodies.

b. Natural killer cells are part of the innate immune system and are responsible for killing infected or cancerous cells. They are not involved in antibody production.

d. Macrophages are phagocytic cells that engulf and destroy pathogens and debris in the body. While they play a crucial role in immune responses, they do not produce antibodies.

Correct Answer is C

Explanation

Explanation: At 2 months of age, infants are recommended to receive the DTaP vaccine, which protects against diphtheria, tetanus, and pertussis (whooping cough). The MMR vaccine protects against measles, mumps, and rubella and is usually administered at a later age. The hepatitis B vaccine is given shortly after birth, and the varicella vaccine is typically administered at 12 months of age.

Incorrect choices:

a. The MMR vaccine protects against measles, mumps, and rubella, not whooping cough (pertussis).

b. The hepatitis B vaccine is typically given shortly after birth, not at 2 months of age.

d. The varicella vaccine is usually administered at 12 months of age, not at 2 months.

Correct Answer is C

Explanation

Explanation: B cells recognize antigens by producing specific receptors on their cell surface, known as antibodies or immunoglobulins. When a B cell encounters an antigen that matches its specific antibody, it binds to the antigen, marking it for destruction or neutralization by other immune cells.

Incorrect choices:

a. Engulfing and processing pathogens is the role of antigen-presenting cells like macrophages and dendritic cells. These cells present processed antigens to other immune cells, including B cells, to trigger an immune response.

b. Cytokines are small proteins that serve as signaling molecules in the immune system. They are produced by various immune cells to regulate immune responses, but they are not directly involved in antigen recognition by B cells.

d. Directly attacking and killing infected cells is the role of cytotoxic T cells during cell-mediated immunity, not B cells during the humoral immune response.
