The anticancer immune defense mechanism involves humoral and cellular responses. The main effector mechanisms of antitumor responses involve the following: the activity of cytotoxic T cells; the activation of macrophages and neutrophils; the activity of cytokines secreted by T cells; and natural killer cell activity. Selected cell populations are responsible for the stimulation or suppression of the immune system against tumor cells. Therefore, the aim of the present study was to evaluate the location, extent and composition of the cellular inflammatory infiltration of tumors in patients with colorectal cancer (CRC)...

Although there is evidence that HCV progresses rapidly in HIV/HCV coinfected patients in comparison with HCV monoinfected, the HIV-, HCV- and host/genetic-related factors, as well as the exact mechanisms implicated in this process are not fully elucidated. Furthermore, cure of HCV in those coinfected seems possible with the new antiviral drugs, but high cost as well as insufficient identification, linkage with care and treatment hamper the achievement of this goal. Research on the subject, could reveal an important prognostic marker for the effectiveness of persuasion of patients with HIV/HCV coinfection with a predicted accelerated fibrosis course, in order to facilitate and prioritize, not in terms of guidelines but in the real life situation, their treatment with a medically just framework...
