Question

t-cell priming refers to the activation, proliferation, and expansion of a naive t cell after its initial encounter with antigen. what is a key feature of this process?click or tap a choice to answer the requires production of cytokines in the lymphoid organ but no direct binding of the t cell to dendritic requires only recognition by the tcr of peptide:mhc primarily occurs when naive t cells enter a tissue and recognize their peptide:mhc complex in that occurs when dendritic cells are first activated by an occurs only when multiple t cells respond at the same time to the same antigen.

Answer 1

T-cell priming involves the direct binding of the T-cell receptor to the peptide:MHC complex presented by dendritic cells in lymphoid organs, triggering T-cell activation and proliferation.

Step-by-step explanation:

T-cell priming is a crucial stage in the adaptive immune response and occurs in the lymphoid organs, such as the spleen and lymph nodes.

A key feature of this process is the requirement for direct binding between the T-cell receptor (TCR) and the peptide: major histocompatibility complex (peptide: MHC) presented by dendritic cells.

This interaction, accompanied by costimulatory signals and the production of cytokines, leads to the activation, proliferation, and expansion of naive T-cells that then differentiate into effector T cells capable of addressing specific antigenic challenges.
