In a study published in Nature on Oct. 11, coinciding with the beginning of IDWeek 2023 in Boston, researchers from Harvard Medical School described EVEscape, a method for anticipating the movements of SARS‑CoV‑2 by predicting potential mutations likely to escape current vaccines and treatments.

In recent years, the introduction of immune checkpoint inhibitors to the oncolytic pipeline has been a significant breakthrough in cancer treatment, but unfortunately some tumors respond only minimally. Besides CTLA-4, and since the approval of PD-1/PD-L1 inhibitors, only the anti-LAG3 strategy (relatlimab, Bristol Myers Squibb Co.) has been good enough to reach the market. In a session dealing with emerging checkpoints beyond PD-1, CTLA-4 and LAG3, Drew Rasco from the START Center for Cancer Care depicted a new player on the ground of immunotherapeutic options.

Cancer treatments for targeting tumor amplifications lag behind those targeting point mutations – and part of the reason may be that amplifications often reside on extrachromosomal DNA (ecDNA). Since ecDNA was first described back in 1965 as minute chromatin bodies in brain cancer cells, the use of large-scale DNA sequencing techniques has revealed the presence of ecDNA across a wide range of cancer types. “The circular structure of ecDNA is associated with increased proto-oncogenic capacity in comparison to linear amplifications. Another key feature is that ecDNA does not contain centromeres,” Roel Verhaak, from Yale School of Medicine, told the audience in a session at the 2023 AACR-NCI-EORTC Conference on Molecular Targets and Cancer Therapeutics in Boston.

The fungus Candida auris has become an urgent clinical problem at a shocking speed. It was not even mentioned in the U.S. CDC’s 2013 reports on antimicrobial threats, but was one of five pathogens on the agency’s 2019 top-tier Urgent Threat List.

The contribution of the soluble form of urokinase-type plasminogen activator receptor (suPAR) as a risk factor for chronic kidney diseases (CKD) is well known. Researchers from Rush University Medical Center, Harvard Medical School and collaborators have now identified D2D3, a suPAR fragment, as responsible for causing double injury, both to the kidney and pancreas, thus resulting in glomerular disease and insulin-dependent diabetes.

In the gastrointestinal tract, intraepithelial lymphocytes are tasked with protecting the epithelium against pathogens and participating in wound repair and correct mucosal barrier functioning. In a study published in the Sept. 15, 2023, issue of Science, researchers at King’s College London and collaborators have identified a specific subset of gamma-delta (γδ) T cells in the human gut, Vγ4 cells, which seems to protect against inflammatory bowel disease (IBD) progression.
