Adaptive Immune System

Front

How do T cells recognize antigens?

Back

T cell receptors (TCRs) bind to specific antigenic peptides presented by major histocompatibility complex (MHC) molecules.

Front

Explain the process of B cell activation and antibody production.

Back

B cell activation involves antigen binding, internalization, presentation to T helper cells, cytokine release, clonal expansion, differentiation into plasma cells, and antibody production.

Front

What is the role of Major Histocompatibility Complex (MHC) in the immune system?

Back

MHC presents antigens to T cells, aiding in immune response and self/non-self recognition.

Front

How does T cell receptor diversity contribute to the adaptive immune response?

Back

T cell receptor diversity enables recognition of various antigens, enhancing the adaptive immune response.

Front

Differentiate between memory and effector immune responses.

Back

Memory immune responses are faster and more robust upon re-exposure to a pathogen due to the presence of memory cells, while effector immune responses are the immediate response to an initial infection involving the activation of various immune cells.

Front

What are the mechanisms involved in the regulation of immune responses?

Back

Cytokines, regulatory T cells, antigen presentation, immune checkpoints

Front

Describe the process of antigen recognition by T cells.

Back

T cells recognize antigens through the T cell receptor (TCR) binding to antigen-presenting cells (APCs) displaying antigen fragments on major histocompatibility complex (MHC) molecules.

Front

Discuss the significance of B cell activation in the immune response.

Back

B cell activation is essential for producing pathogen-specific antibodies, aiding in pathogen neutralization, marking for destruction, and memory cell formation.

Front

Why is Major Histocompatibility Complex (MHC) important for immune recognition?

Back

MHC presents antigens to T cells, aiding in immune response initiation.

Front

How are memory immune responses different from effector immune responses?

Back

Memory immune responses are faster and more robust due to memory cells, while effector immune responses are the immediate response to the initial exposure.
