Historical shifts, geographic biases, and biological constraints shape mammal species discovery

Journal of Systematics and Evolution, EarlyView.
Taxonomic descriptions of mammals have become more robust from 1990 to 2025, with increased specimen sampling, broader comparisons, and more integrative methods. However, disparities remain: tropical and small‐bodied species are less comprehensively described, reflecting ongoing geographic and biological biases.

GAS6 signaling tempers Th17 development in patients with multiple sclerosis and helminth infection.

PLoS Pathogens, 2020
Multiple sclerosis (MS) is a highly disabling neurodegenerative autoimmune condition in which an unbalanced immune response plays a critical role. Although the mechanisms remain poorly defined, helminth infections are known to modulate the severity and ...

Differences in the gene expression profiles of haemocytes from schistosome-susceptible and -resistant biomphalaria glabrata exposed to Schistosoma mansoni excretory-secretory products. [PDF]

PLoS ONE, 2014
During its life cycle, the helminth parasite Schistosoma mansoni uses the freshwater snail Biomphalaria glabrata as an intermediate host to reproduce asexually generating cercariae for infection of the human definitive host.

Anaemia Among Mother–Child Dyads in India: Trends, Drivers, and Future Projections

Maternal &Child Nutrition, EarlyView.
ABSTRACT Anaemia among mothers and their children is a widespread public health challenge with profound consequences for individuals and societies. While anaemia has been studied separately in women and children, there remains a literature gap examining anaemia in mother‐child dyads, limiting insights on interventions that may simultaneously address ...

Mixed Signals: T Cells as Architects of IgE Immunity

Immunological Reviews, Volume 339, Issue 1, May 2026.
ABSTRACT Food allergen‐specific IgE can cause significant pathology, yet the pathways that generate pathogenic, high‐affinity IgE remain incompletely understood. Increasing evidence suggests that IgE responses arise from the integration of multiple, and sometimes opposing, T cell–derived cues.

Genomic introgression mapping of field-derived multiple-anthelmintic resistance in Teladorsagia circumcincta [PDF]

, 2017
Preventive chemotherapy has long been practiced against nematode parasites of livestock, leading to widespread drug resistance, and is increasingly being adopted for eradication of human parasitic nematodes even though it is similarly likely to lead to ...

Molecular Engineering of the Helminth TGF‐β Mimetics, TGM1 and TGM4, Reveals a Novel Antagonist of TGF‐β Signaling in Fibroblasts

The FASEB Journal, Volume 40, Issue 7, 15 April 2026.
The helminth TGF‐β mimic TGM4 activates SMAD signaling in macrophages and T cells through canonical TGF‐β receptors and the CD44 co‐receptor, through Domains 1–5 (D1‐5). In fibroblasts, which express lower levels of CD44, TGM4 binds but does not transduce a signal; furthermore, it inhibits activation by agonist ligands such as TGF‐β itself, in a manner

The role of T cells in sepsis of distinct infectious aetiologies

Clinical and Translational Discovery, Volume 6, Issue 2, April 2026.
Pathogen‐specific sepsis induces mitochondrial dysfunction in T cells, leading to functional alterations. Single‐cell transcriptomics reveals subtype‐specific impairments involving reactive oxygen species accumulation, mtDNA damage, calcium dysregulation, and metabolic reprogramming.
