Robust IL-2-dependent antitumor immunotherapy requires targeting the high-affinity IL-2R on tumor-specific CD8+ T cells
Introduction Interleukin (IL)-2 was the first Food and Drug Administration approved immunotherapy for use in patients with metastatic melanoma and renal cell carcinoma.1 2 However, the use of recombinant IL-2 (Proleukin/aldesleukin) has been problematic due to low response rates, off-target effects, and severe dose-dependent toxicities. Due to its potent T-cell…

New study reveals details across 20 diverse i
The completion of the full “telomere-to-telomere” (T2T) human genome last year emphasized that genome sequences that were previously thought to be “complete” were not, in fact, complete at all. Moreover, many recent genomes are sequenced with short-read sequencing technologies, which fragment DNA into short segments, typically 150-300 base pairs long,…

Melatonin Suppresses Cyclic GMP-AMP Synthase-Stimulator of Interferon Genes Signaling and Delays the Development of Hearing Loss in the C57BL/6J Presbycusis Mouse Model
Melatonin supplementation has been shown to delay age-related hearing loss (ARHL) progression.
