Many cases of human immunodeficiency virus (HIV)-1 infection can be effectively treated with existing drugs, but they can lose efficacy over time because of the emergence of resistance. In an effort to generate next-generation drugs, Chinese researchers at the Chinese Academy of Medical Sciences & Peking Union Medical College and other institutions synthesized a series of peptidomimetics against the viral protease, in which they extended the therapeutically effective hydroxyethyl sulfonamide scaffold using an amino acid linker. They reasoned that the linker could allow the drug to make additional contacts with the protease.

Lung cancer is the second most frequent cancer worldwide, and it accounts for 18% of all cancer-related deaths. Most cases of lung cancer involve non-small-cell lung cancer (NSCLC), in which therapy with immune checkpoint inhibitors (ICIs) can improve prognosis, yet up to 75% of patients fail to respond to it. Researchers at the Chinese Academy of Medical Sciences & Peking Union Medical College have identified potential metabolic markers that may help predict which patients are more likely to respond to ICI therapy.

Oncolytic viruses trigger immunogenic cell death in tumors, releasing signals that activate innate immune cells and promote tumor-specific T-cell responses. While some oncolytic viruses, including FDA-approved T-VEC, have shown safety and some clinical benefit, their limited effectiveness as standalone treatments underscores the need for combination therapies.

Investigators from the Chinese Academy of Medical Sciences & Peking Union Medical College presented data from a study that investigated the regulatory mechanisms of intestinal epithelial cell (IEC) death and intestinal inflammation.
