Tcells surround a cancer cell to finish it off, but such interactions do not always end with the T cells victorious. Researchers from Penn detail how cancer cells can prompt T cells to ingest bits of cancer cell membrane, a process known as trogocytosis. The cancer may evade immune detection as a result.

When the enzyme DOT1L is not functional, spermatogonial stem cells become exhausted, leading to a failure of sperm cell development. This crucial role for DOT1L places it in rarefied company as one of just a handful of known stem cell self-renewal factors, a Penn Vet team found. (Image: Courtesy of Jeremy Wang)
