Daftar Isi:
- Tuberculosis (TB) is caused by Mycobacterium tuberculosis (M.tb) and is one of the significant mortality causes WHO (2012). The primary immune response in TB pathogenesis is Cell Mediated Immunity (CMI), roled by T lymphocytes. Interleukin-2 (IL-2) is a growth factor for T lymphocytes. Gamma Interferon is the key cytokine in M.tb infection control, synthezised by T lymphocytes. An effective vaccination strategy is achieved by giving vaccine which is able to stimulate T lymphocytes in synthezising cytokines. The 38 kDa M.tb protein is potential in the vaccine development program, because it has specific epitopes for T lymphocytes. The aim of this study was to know how to determine that the 38 kDa recombinant protein of M.tb Malang strain could induce cellular immune response by IL-2 and IFN-γ synthezised by T lymphocytes. The study was carried out by an experimental in vitro study on PBMC from healthy endemic subjects, those having TB contact, and the TB patients themselves. PBMC from subjects was cultured with 38 kDa recombinant protein of M.tb Malang strain, with PPD and without any protein. The analysis of IL-2 and IFN-γ used flowcytometry. The result showed that the highest percentage of IL-2 was found in the culture with 38 kDa recombinant protein of M.tb Malang strain, in healthy endemic (p=0.000) and in those who had TB contact (p=0.000). the highest percentage of IFN-γ was found in the culture with 38 kDa recombinant protein of M.tb Malang strain, in healthy endemic (p=0.007) and those who had TB contact (p = 0.105). The 38 kDa recombinant protein of M.tb Malang strain was able to induce IL-2 and IFN-γ synthezised by TCD3+ lymphocytes from healthy endemic subjects and those who had TB contact.
