Scientists must actively advocate for infrastructure development and funding of emerging research directions through collective efforts. In India, this has been crucial to help reverse the brain drain and enable equitable contributions to research and development at the global level.
Contractile activity of both the epithelium and underlying mesenchyme are required for epithelial deformation and cell fate acquisition during early mouse hair follicle development. Subsequently, localized basement membrane remodelling facilitates the release of tension-generated pressure to promote cell divisions, tissue fluidification and downgrowth of the developing hair follicle.
The chemoresistant and immunoevasive characteristics of leukaemia stem cells (LSCs) impede the treatment efficacy for acute myeloid leukaemia (AML). We find that inhibiting the tyrosine phosphatase SHP-1 effectively alters the metabolic state of LSCs, making them more susceptible to chemotherapy and immune surveillance in AML.
Mechanical forces are ubiquitously present in biology. In recent years, it has become clear how plasma membranes detect these forces — but how do intracellular organelles such as lysosomes do the same, and what might be the functions of such intracellular mechanosensing? Answers may come through a report of a lysosomal mechanosensitive ion channel, TMEM63.
Li, Guo, Wang and colleagues show that the ion channels TMEM63 in Drosophila and TMEM63A in mouse mediate lysosomal mechanosensitivity and modulate lysosomal morphology and function.
As a major microenvironmental component in B cell lymphomas, T cells are highly relevant for current immunotherapeutic treatment strategies of such tumours. A study now provides an unprecedented multimodal insight into the composition and features of T cell subsets of the four main types of nodal B cell non-Hodgkin lymphoma.
Roider, Baertsch et al. present a spatially resolved resource map of the T cell infiltration landscape across and within patients with distinct B cell non-Hodgkin lymphoma entities.
The generation of clathrin-coated vesicles during endocytosis requires the co-ordinated recruitment of dozens of proteins to the plasma membrane. We discovered that the plant TPLATE (or TSET) complex (TPC) undergoes biomolecular condensation through interactions with plasma membrane phospholipids and, via weak multivalent interactions, recruits clathrin and other endocytic proteins to facilitate the efficient progression of endocytosis.
Dragwidge et al. report that the plant endocytic complex, the TSET–TPLATE complex, undergoes biomolecular condensation through interactions with plasma membrane phospholipids and recruits clathrin for endocytosis.
Despite a growing understanding of the immunostimulatory properties of mitochondrial DNA (mtDNA), little is known about how and why mtDNA escapes its mitochondrial confines. A study now describes an endosomal trafficking pathway that facilitates mtDNA egress and provides an additional mechanism of mtDNA release in vitro.
Newman et al. show that, upon mitochondrial DNA (mtDNA) replication stress, enlarged nucleoids are trafficked to endosomes. Endosomal rupture releases mtDNA into the cytoplasm, triggering cGAS–STING activation and innate immune signalling.
In this piece, I share a personal encounter that underscores the glaring gaps in conference accessibility and challenges faced by disabled academics. I reveal historical biases and resistance to change and propose ways to transform conferences into more inclusive spaces, ensuring that all scientists can fully participate in the scientific discourse.
Yang et al. identify an essential role for ECSIT in promoting memory CD8+ T cell development by modulating fumarate synthesis and altering TCF-1 activity, thereby impacting host responses during viral infection and tumorigenesis.
Zwick et al. examine longitudinal transcriptional patterns across the entire mouse and human small intestine and find that, in both species, the small intestine comprises five domains of nutrient absorption and three regional stem cell populations.
Xu, Yu, Zhang, Ma, He and colleagues show that SHP-1 inhibition causes increased glycolysis and oxidative phosphorylation through PFKP in leukaemia stem cells, thereby promoting immunosurveillance and chemosensitivity in acute myeloid leukaemia.
How do metabolic stresses trigger catabolic autophagy for cell survival? A study now reveals that the metabolite sensor Pho81 integrates into and activates the kinase activity of the Atg1 complex for pexophagy triggered by phosphate starvation. This demonstrates the plasticity of the autophagy-initiating Atg1 complex.
