The arrangement of a mother's genes could affect the sexual orientation of her son, according to a new study. The finding, detailed in the February issue of the journal Human Genetics , adds fuel to the decade-long debate about whether so-called "gay genes" might exist. The researchers examined a phenomenon called "X chromosome inactivation" in 97 mothers of gay sons and mothers whose sons were not gay.

Adoptive transfer of T cells genetically modified to express cancer-specific receptors can mediate impressive tumor regression in terminally ill patients. In addition, the lack of positive costimulation at the tumor site can further dampen T cell response. Thus, as T cell genetic engineering has become clinically relevant, we aimed at enhancing T cell antitumor activity by genetically diverting T cell-negative costimulatory signals into positive ones using chimeric costimulatory retargeting molecules and which are composed of the PD1 extracellular domain fused to the signaling domains of positive costimulatory molecules such as CD28 and BB. After characterizing the optimal PD1 chimera, we designed and optimized a tripartite retroviral vector that enables the simultaneous expression of this chimeric molecule in conjunction with a cancer-specific TCR.
