The multidrug resistance (MDR) is one of the main reasons for chemotherapeutic failures in cancer patients. The overexpression of mdr1 gene product, P-glycoprotein (Pgp), leads to the appearance of resistant tumor cells. In the previous paper (Erokhina, 1997) we have demonstrated that the first

The Gag proteins of replication-competent retroviruses direct budding at the plasma membrane and are cleaved by the viral protease (PR) just before or very soon after particle release. In contrast, defective retroviruses that bud into the endoplasmic reticulum (ER) have been found, and

To identify prostate cancer-associated Ags, tumor-reactive T lymphocytes were generated using iterative stimulations of PBMC from a prostate cancer patient with an autologous IFN-gamma-treated carcinoma cell line in the presence of IL-2. A CD8+ T cell line and TCR alphabeta+ T cell clone were

OBJECTIVE It has recently been recognised that anticancer chemotherapy can elicit an immunogenic form of apoptosis characterised by the exposure of calreticulin (CRT) on the surface of dying tumour cells, entailing an immune response that contributes to the therapeutic outcome. CRT exposure has been

Primary effusion lymphoma (PEL), a subtype of non-Hodgkin's B-lymphoma, is an aggressive neoplasm caused by Kaposi's sarcoma-associated herpesvirus (KSHV) in immunosuppressed patients. Endoplasmic reticulum (ER) stress induces activation of the unfolded protein response (UPR), which induces
