 AB    Infections are major cause of illness and death amongst elderly people.
       Peripheral blood CD8+ T lymphocytes -which play a crucial role in host
       defence against viral infections-. are divided in subsets based upon the
       expression of several cell and activation markers. Since in senescence
       changes in peripheral blood CD8+ T lymphocyte compartment have been
       described, studies were performed to determine whether in aging there
       are variations in the peripheral blood CD8+CD38+, CD8+CD57+,
       CD8+HLA-DR+, CD8+CD45RA+ and CD8+CD45RO+ cell subset. A decrease in the
       CD8+CD45RA+ lymphocytes was observed, indicating that variations in the
       CD8+ compartment can take place with ageing.
