New research from the UPMC Hillman Cancer Center and the UPSOM (University of Pittsburgh School of Medicine) showed how tumors utilize the body’s regulators of resistance for their own advantage. The results can be utilized to develop the latest generation of immune treatments to fight with various cancers. Dario Vignali—Senior Author of the study—said, “While cancer immunotherapy medications that obstruct inhibitory cell surface molecules such as PD1 have transformed cancer care, only around 20% of individuals clear their tumors. Our findings revealed a previously unidentified biological mechanism that discloses new therapeutic advances to endorse anti-tumor immunity.” The study was published in Nature Immunology.
Vignali along with his team aimed at a group of immune cells known as Tregs (regulatory T cells), which help in maintaining delicate stability in the immune system. They do that by defusing immune responses, maintaining the system sensitive adequate to catch threats, but not so responsive that they outcome in autoimmunity, by attacking the normal cells. To gain this control, Tregs discharge small proteins known as cytokines that can have dissimilar effects on cells. Earlier research, counting findings from Vignali’s laboratory, had shown that tumors cunningly take advantage of Tregs within the tumor’s microenvironment to shut down killer T cells and escape the body’s immune defenses.
Recently, the UPMC Hillman Cancer Center along with MWRI (Magee-Women’s Research Institute) was in the news as its study showed that targeting stem-like cells can avert recurrence of ovarian cancer. Reportedly, ovarian cancer is not the most ordinary form of cancer, but it is amongst the deadliest. Since about 70% of cases reappear. A new study has targeted the root of reappearance with new drugs planned at annihilating stem-like ovarian cancer cells. The research was published in the Cell Reports.
