Abstract: A method for distinguishing replicatively senescent T cells from replicatively non-senescent T cells in a cell population comprises the steps of: (1) providing a cell population of peripheral blood mononuclear cells; (2) reacting the cell population with a first monoclonal antibody specific for CD3 antigens which is present on all T cells, the antibody being labeled with a first detectable label, so that the monoclonal antibody binds to all T cells in the cell population; (3) simultaneously reacting the cell population with a second monoclonal antibody specific for CD28 antigen, the antibody being labeled with a second detectable label distinguishable from the first detectable label, so that the second monoclonal antibody binds to T cells positive for CD28; and (4) in the cell population of peripheral blood mononuclear cells, detecting the T cells that simultaneously react with the first monoclonal antibody and the second monoclonal antibody by observing the first detectable label bound to the cells simultaneously with the second detectable label bound to the cells, thereby distinguishing replicatively senescent T cells, which are CD28-negative, from replicatively non-senescent T cells, which are CD28-positive, and determining any of: (a) the number of replicatively senescent T cells in the cell population; (b) the number of replicatively non-senescent T cells in the cell population; or (c) the proportion of replicatively senescent T cells to replicatively non-senescent T cells in the cell population. The method can also be used to separate and isolate cells showing immunological senescence from non-senescent cells.

First Claim:
Show all 13 claims
I claim:     1. A method to identify replicatively senescent T-cells in a sample containing T-cells comprising:
  • determining the presence or absence of CD28 and CD3 on a surface of the cells of said sample; and
  • identifying replicatively senescent T-cells as possessing CD3 (CD3+) and lacking CD28 (CD28-); wherein replicatively senescent T-cells are characterized as being unable to undergo cell division and wherein a first monoclonal antibody that binds to CD3 and a second monoclonal antibody that binds to CD28 are used to identify the presence or absence of CD3 and CD28 on the surface of said cells.
