Tumour‐Derived Extracellular Vesicles Reprogramme Tumour‐Associated Macrophages Into Immunosuppressive Phenotype via NOD1 Signalling in Clear Cell Renal Cell Carcinoma

Journal of Extracellular Vesicles, Volume 15, Issue 6, June 2026.
ABSTRACT Clear cell renal cell carcinoma (ccRCC)‐derived extracellular vesicles (EVs) play a pivotal role in myeloid cell differentiation toward immunosuppressive phenotypes, yet the underlying mechanisms remain poorly understood. Through integrated single‐nucleus RNA sequencing, EV proteomics, and phenotype validation, we identified NOD1, a pattern ...

Enterococcus faecalis Extracellular Vesicles Deliver the Bacterial GTPase Obg to Hijack mTOR Signalling in Hepatocellular Carcinoma

Journal of Extracellular Vesicles, Volume 15, Issue 6, June 2026.
E. faecalis is enriched in HCC tissue and can promote liver tumourigenesis by activating mTOR signalling pathway. Obg derived from E. faecalis extracellular vesicles (EVs) is a GTPase physically interacts with mTOR, and acts as an interkingdom activator of mTOR. EF‐Obg expression level in HCC tissue correlates with poor prognosis in HCC patients.

RASGRP1 Deficiency Manifesting as Severe Vasculopathy and Fatal Autoimmune Hemolytic Anemia

eJHaem, Volume 7, Issue 3, June 2026.
ABSTRACT Background RASGRP1 deficiency is a rare inborn error of immunity characterized by immunodeficiency, autoimmunity, and lymphoproliferation. Results We report a 5‐year‐old male with novel homozygous splice‐donor mutations in RASGRP1(c.1720+1G>A and c.1720+2T>C) who presented with severe vasculopathy (ischemic stroke and thrombosis), secondary ...

The Role of N6‐Methyladenosine Modification in Health and Disease

MedComm, Volume 7, Issue 6, June 2026.
N6‐methyladenosine (m6A) is the most prevalent internal RNA modification in eukaryotes, acting as a pivotal epitranscriptomic regulator of RNA metabolism. This modification plays a dual role: it maintains physiological homeostasis under normal conditions but drives disease progression when dysregulated.

Pathways of Protein Secretion in Prokaryotes and Eukaryotes: Molecular Mechanisms, Biological Functions, and Therapeutic Opportunities

MedComm, Volume 7, Issue 6, June 2026.
This graphical abstract delineates noncanonical protein secretion systems across eukaryotes and prokaryotes. Eukaryotic UcPS covers four ER–Golgi bypass pathways, enabling rapid leaderless protein export via direct transmembrane translocation or vesicle‐mediated release.

Depletion of microglial compensation in glial network: Disease‐associated response dynamics in the revised amyloid hypothesis

Neuroprotection, Volume 4, Issue 2, Page 131-142, June 2026.
The critical transition from amyloid pathology to irreversible neuronal loss in Alzheimer's disease hinges on the microglial response. This review aims to systematize the patterns of how microglia react within the glial context. Abstract Microglia mount coordinated, stage‐dependent compensatory programs in response to early amyloid β (Aβ) accumulation ...
