“…30,41 The role of several factors in the development of MOF and subsequent death after ischemia, shock, trauma, and hemorrhage (such as lipid peroxidation, neutrophil activity, inducible nitric oxide synthase, and NF-κB) have been studied in several previous studies. 14,24,42,43 However, the role of T-cell and subgroup functions in development of tissue injury and subsequent MOF remains to be further evaluated. 30 CD4+ T lymphocytes, also known as helper T cells, mainly participate in promotion of the cell-mediated immune response, augmentation of immunoglobulin (Ig)M and IgG2 synthesis by B cells, activation of macrophages, and promotion of antibody-mediated immune responses, which lead to IgG1 and IgE responses.…”
