Thymosins stimulate maturing T cells to develop surface antigen receptors, making them ____________ receptor

Reticuloendothelial (RE) cells in the thymus test T cells by presenting self-antigens to them, acting as the final ____________

Inability to recognize the RE cells, especially their MHC antigens, results in ____________ selection

Reacting to self-antigens leads to ____________ selection of T cells

2% of the T cells that reach the thymus leave as ____________ T cells

Naive T cells leave the thymus and colonize lymphatic tissues and organs, becoming cells of cellular ____________

Cytotoxic T (TC) cells are known as the 'Effectors' of cellular ____________

T lymphocytes are born in the red bone marrow

Thymosins stimulate T cells to develop surface antigen receptors in the spleen

Reticuloendothelial (RE) cells present self-antigens to test T cells in the thymus

Naive T cells leave the thymus and colonize lymphatic tissues and organs throughout the body

Cytotoxic T cells are known as 'Effectors' of cellular immunity

Helper T cells promote B cell action and nonspecific immunity

Less than 2% of T cells that reach the thymus leave as immunocompetent T cells

Memory T cells are activated by interaction with MHC-II displayed antigens

Memory T cells are responsible for memory in humoral immunity.

Antigen presenting cells migrate to the nearest lymph node and present antigens to B cells.

Cytotoxic T cells are activated by interaction with MHC-II displayed antigens.

Clonal selection is a process that occurs during T cell activation.

Memory cells have a primary function of inhibiting multiplication of other T cells.

Antigen presentation involves an APC encountering, processing, and presenting an antigen to T cells.

Helper T cells are activated by co-stimulation during T cell activation.
