Myelopeptides effect on longevity and immunological parameters in mice with congenital immunodeficiency
By Mikhailova AA, Sorokin SV, Komponiec NA
Myelopeptides (MP) are regulatory molecules produced by animal and human bone marrow cells. A highly purified MP fraction has been isolated from supernatant of the porcine bone marrow cell culture by gel chromatography on Sephadex G-25 and HPLC. MP correct defective antibody response to SRBC in MRL/lpr mice with spontaneous autoimmune disease and increase hemoglobin level in Wv/Wv mice with congenital anemia. Hemoglobin enhancement in Wv/Wv mice is connected with MP influence of differentiation and proliferation of hemopoietic stem cells. MP correction of immunological parameters in MRL/lpr mice resulted in 2-fold prolongation of their life span.
