Gasdermin D palmitoylation: to cleave or not to cleave?

Recent studies have identified Cys in gasdermin D (GSDMD) as a highly targeted regulatory module controlling pyroptosis. Using chemical biology and genetic models, Du, Healy et al. recently identified GSDMD palmitoylation as a key regulatory step in GSDMD activation.

A novel high-throughput screening strategy for targeting alpha-synuclein and other long-lived proteins.

Small-molecule high-throughput screening (HTS) campaigns have frequently been used to identify lead molecules that can alter expression of disease-relevant proteins in cell-based assays. However, most cell-based HTS assays require short compound exposure periods to avoid toxicity and ensure that compounds are stable in media for the duration of the exposure. This limits the ability of HTS assays to detect inhibitors of the synthesis of target proteins with long half-lives, which can often exceed the exposure times utilized in most HTS campaigns.

Psychology at the table: Voices of elected officials and advocates.

Psychologists have generally not considered advocacy a significant part of their professional activities. At the same time, federal and state public policies create laws and regulations that significantly impact the profession and the public. This article encourages psychologists to become involved in public policy and describes various methods for becoming engaged.

The Period protein homolog LIN-42 regulates germline development in C. elegans.

Germline stem cells are maintained in the distal region of the C. elegans gonad. These cells undergo mitotic divisions, and GLP-1/Notch signaling dictates whether they remain in this state.
