POSTECH and ImmunoBiome researchers uncover a novel microbiota-Tfh cell axis to enhance antibody production and mucosal vaccine efficiency.
Scientists discovered key genetic factors that determine whether a T cell acts as a powerful disease fighter or enters an ineffective, exhausted state. Turning off two transcription factors allowed exhausted T cells to regain their ability to kill tumors. The findings could help scientists engineer more powerful T cells for cellular therapies such as adoptive cell transfer (ACT) and CAR T cell therapy.
Early cancer detection often relies on complex, invasive, and time-consuming staining procedures. A research team from Southeast University has developed a novel "label-free" biosensor that uses the physics of "band folding" to unlock high-density hidden electromagnetic modes in the sub-terahertz range. This technology creates a rich spectral fingerprint that can distinguish between normal cells and cancer cells of varying malignancy without chemical markers. By correlating macroscopic electromagnetic signals with microscopic cellular biomass density, this method offers a safe, rapid, and non-destructive path for future clinical cancer screening.
A study of U.S. veterans led by investigators at Mass General Brigham, VA Boston Healthcare System, and the Melanoma Research Alliance has identified a possible link between exposure to the Agent Orange herbicide and a rare melanoma subtype less likely to be related to sun exposure. The authors of the study, published in JAMA Dermatology, say this link warrants further examination to inform diagnostic strategies for people who may be at a greater risk for acral melanoma.
