SARS-CoV-2 nsp15 Preferentially Degrades AU-Rich dsRNA via Its dsRNA Nickase Activity

[Nucleic Acids Research] The authors prepared numerous RNA substrates, including both long substrates mimicking the viral genome and short defined RNA, to clarify the substrate preference and cleavage pattern of SARS-CoV-2 nsp15.

Functional CRISPR Screens in T Cells Reveal New Opportunities for Cancer Immunotherapies

[Molecular Cancer] Investigators bridge the gap between discovering element genes to a specific process of T cell activities and apprehending these genes in the global T cell life cycle, deepened the understanding of T cell biology in tumour immunity, and outline CRISPR screens resources that might facilitate the development and implementation of cancer immunotherapies in the clinic.

Tertiary Lymphoid Structural Heterogeneity Determines Tumour Immunity and Prospects for Clinical Application

[Molecular Cancer] The authors explore the dynamic interactions among T and B cell subpopulations of varying phenotypes that contribute to the structural and functional diversity of TLS, examining both existing and emerging techniques for TLS imaging and induction, focusing on cancer immunotherapies and biomaterials.

Immunogenic Material Vaccine for Cancer Immunotherapy by Structure-Dependent Immune Cell Trafficking and Modulation

[Advanced Materials] Scientists manipulated the immunopotentiator manganese into six differing structures that resemble the architectures of two types of pathogens. They revealed that innate immune cells accurately sense and respond to the architectures, of which two outperformed material candidates showedhigher competence in creating local pro-inflammatory environment with promoted innate immune cell influx and stimulatory effects on multiple subsets of dendritic cells.

Tumor-Targeted Therapy with BRAF-Inhibitor Recruits Activated Dendritic Cells to Promote Tumor Immunity in Melanoma

[Journal For Immunotherapy Of Cancer] Scientists investigated therapy-mediated immunological alterations in the tumor microenvironment and tumor-draining lymph nodes in the D4M.3A preclinical melanoma mouse model by using high-dimensional multicolor flow cytometry in combination with multiplex immunohistochemistry.

Canada Likely to Miss WHO’s Hepatitis C Elimination Target, Research Shows

[University of Waterloo] Canada will not reach the original World Health Organization's (WHO) target of eliminating the Hepatitis C virus by 2030 and lags in comparison to other developed countries, a new study led by researchers at the University of Waterloo has found.

Arginine Ingestion Inhibits Phagocyte Invasion in Eccentrically Contracted Rat Fast-Twitch Muscle

[Journal of Muscle Research and Cell Motility] Scientists investigated whether prior ingestion of L-arginine, a nitric oxide precursor, inhibited eccentric contraction-induced macrophage invasion.

KLF13 Promotes VSMCs Phenotypic Dedifferentiation by Directly Binding to the SM22α Promoter

[Journal of Cellular Physiology] The authors investigated the relationship between KLF13 and SM22α expression in normal and atherosclerotic plaques by bioanalysis, and observed a significant increase in KLF13 levels in the atherosclerotic plaques of both human patients and ApoE−/− mice.

Mitochondrial CypD Acetylation Promotes Endothelial Dysfunction and Hypertension

[Circulation Research] Researchers studied cyclophilin D (CypD) acetylation in patients with essential hypertension, defined a pathogenic role of CypD acetylation in deacetylation mimetic CypD-K166R mutant mice and endothelial-specific general control of amino acid synthesis 5 like 1–deficient mice using an angiotensin II model of hypertension.
