How do T cells become activated quizlet?
In this manner, how do T cells become activated?
Helper T cells become activated when they are presented with peptide antigens by MHC class II molecules, which are expressed on the surface of antigen-presenting cells (APCs). Once activated, they divide rapidly and secrete cytokines that regulate or assist the immune response.
One may also ask, at which anatomical sites do naive T cells encounter antigen? 1) Naive T cells encounter antigen and start the primary immune response in a secondary lymphoid tissue. 2)Lymph nodes: The pathogen and dendritic cells that have ingested the pathogen are carried to the nearest lymph node in afferent lymph.
what is the function of T cells quizlet?
promote the activity of other immune cells in the acquired immune response.
When activated can help activate B cells?
It is likely that, as with any pathogen antigen, concentrations of TI-1 antigens are low during the early stages of infections in vivo; thus, only antigen-specific B cells are likely to be activated and these will produce antibodies specific for the TI-1 antigen.
