Nramp1 and NrampB Contribute to Resistance against Francisella in Dictyostelium

Frontiers in Cellular and Infection Microbiology, 2017
The Francisella genus comprises highly pathogenic bacteria that can cause fatal disease in their vertebrate and invertebrate hosts including humans. In general, Francisella growth depends on iron availability, hence, iron homeostasis must be tightly ...

Mechanosensing in Dendritic Cells

Immunological Reviews, Volume 337, Issue 1, January 2026.
ABSTRACT Since their discovery, dendritic cells have been recognized for their unusual capacity to sense and respond to physical stimuli within their environment. However, it took nearly two decades—and the advent of mechanobiology—to elucidate the underlying mechanisms and functional implications of this mechanical hypersensitivity. In this review, we

Iron metabolism and resistance to infection by invasive bacteria in the social amoeba Dictyostelium discoideum

Frontiers in Cellular and Infection Microbiology, 2013
Dictyostelium cells are forest soil amoebae, which feed on bacteria and proliferate as solitary cells until bacteria are consumed. Starvation triggers a change in life style, forcing cells to gather into aggregates to form multicellular organisms ...

Cell stress by phosphate of two protozoa tetrahymena thermophila and tetrahymena pyriformis [PDF]

, 2017
Phosphorus is one of the bioelements most needed as a compound cell by living organisms. Phosphorus is involved in several pathologies: in human with bone and kidney diseases, in mammals with metabolism disorder (glucose, insulin···), in microorganisms ...

Elastic Energy Storage in Biological Materials: Internal Stresses and Their Functionality

Advanced Materials, Volume 37, Issue 51, December 23, 2025.
Harnessing and storing internally generated elastic energy is a clever strategy by biological materials to perform functions like shape transformation, movement, and predation. This review explores how biological systems manipulate mechanisms like atomic or protein integration into minerals, protein conformational shifts, phase transitions, and osmotic

Astragaloside IV alleviates hypoxic pulmonary hypertension by inhibiting RELM‐β to reduce PINK1/Parkin‐mediated mitophagy in pulmonary artery smooth muscle cells (PASMCs)

British Journal of Pharmacology, Volume 182, Issue 24, Page 5933-5952, December 2025.
Background and Purpose Hypoxic pulmonary hypertension (HPH) is a chronic disorder marked by irreversible pulmonary vascular remodelling (PVR) and pulmonary artery smooth muscle cell (PASMC) dysfunction. Astragaloside IV (AS‐IV), a natural saponin from Astragalus, shows potential in HPH management. This study explores AS‐IV's protective effect on PVR in

Shining a Light on Skeletal Muscle Regeneration: Red Photobiomodulation Boosts Myoblast Differentiation In Vitro

The FASEB Journal, Volume 39, Issue 21, 15 November 2025.
Red (635 ± 10 nm) photobiomodulation (PBM) with an energy density of 4 J/cm2 enhances myogenic differentiation of murine skeletal myoblasts by promoting F‐actin assembly, modulating bioelectrical plasmamembrane properties, and increasing the expression of myogenic markers, mitochondrial biogenesis and activity, and secretion of promyogenic ...

Taxonomy of Nephroselmis viridis sp. nov. (Nephroselmidophyceae, Chlorophyta), a sister marine species to freshwater N. olivacea [PDF]

, 2011
The genus Nephroselmis (Nephroselmidophyceae), which had been placed in the Prasinophyceae, is one of the primitive green flagellates that are important to our understanding of the early evolution of green plants. We studied a new species of Nephroselmis
