Cell Proliferation, EarlyView.This study provides the first definitive identification of tunnelling nanotubes (TNTs) between cultured osteocytes and shows TNT‐mediated lysosome transfer from healthy to stressed cells, restoring autophagic flux and preventing apoptosis. This discovery of transcellular autophagy reveals a new survival mechanism in osteocytes, offering potential ...

Relative potencies of different cytochalasins for the inhibition of phagocytosis in ciliates
, 1998 Ciliate actins have been reported to exhibit an unusual degree of sequence divergence, within the phylum Ciliophora, and when compared to actins from other organisms.

The FEBS Journal, EarlyView.Mitochondria can be transferred from bone marrow cells to cancer cells in acute myeloid leukaemia and multiple myeloma, boosting tumour energy production, growth, and drug resistance. This review highlights key transfer mechanisms and shows how targeting mitochondrial movement and dynamics may offer new therapeutic strategies to limit cancer ...

The LAV‐BPIFB4‐Platelet‐CD47 Axis: A Novel Mechanism Associated With Immune Resilience in Longevity
Aging Cell, Volume 25, Issue 7, July 2026.Centenarians display elevated CD47+ reticulated platelets, a trait recapitulated in LAV‐BPIFB4 carriers on total platelet pool. LAV‐BPIFB4 drives an early acquirement of CD47 surface expression, enabling platelets to suppress monocyte IL‐6 release. rhLAV‐BPIFB4 phenocopies the effects in non‐genetic carriers, establishing the platelet–CD47–monocyte ...

Immunology &Cell Biology, Volume 104, Issue 6, Page 595-608, July 2026.VitBAg antigen presentation is promoted through a cytosolic pathway that reaches ligand‐receptive MR1 to present to MAIT cells, like the riboflavin transport pathway. Riboflavin solute carrier transporters can promote this MR1 presentation, but they are not essential for this role, suggesting redundant pathways to uptake VitBAg.

Cytochalasins from endophytic Diaporthe sp. GDG-118
, 2019 The plant Sophora tonkinensis, possessed a range of active compounds, was traditionally used in the medicine of Chinese minorities. Endophytic fungi were isolated from this plant, of which the fungus Diaporthe sp. GDG-118 was fermented and extracted with

Immunology, Volume 178, Issue 3, Page 417-427, July 2026.Inflammatory bowel disease (IBD), comprising ulcerative colitis (UC) and Crohn's disease (CD), is a recognised gastrointestinal disorder. Mycobacterium avium subspecies paratuberculosis (MAP) is implicated in IBD pathogenesis. Persistent exposure and active infections by MAP may contribute to the unsilencing of human endogenous retroviruses (HERV ...
