AbstractAbstract
[en] An increased response to PVP was observed after adult mouse thymectomy and was partially reversed either by thymus implantation or by a single injection of thymic cells. In addition, an injection of thymic cells was found to reduce the response to PVP in normal recipients. An enhanced response to PVP was measured in B mice compared to that of normals. In such mice reduction of the response to PVP was observed when repeated doses of thymus cells were administered. Lower doses of HC resistant thymus cells strongly inhibited the response to PVP. The cells involved in the thymus regulatory function appear to be radiosensitive, since it was shown that radiation by itself resulted in an increased response to PVP. This inhibitory function of the thymus seems to disappear relatively early in progression of life, as seen by an increased response to PVP in elder mice. These results indicate that a T cell population exerts a regulatory function in the immunological response to PVP that was previously considered to be thymus independent
