Dendritic Cell α‐Ketoglutarate Regulates Tfh Polarization in Allergy

Allergy, EarlyView.
Allergen induces a dendritic cell metabolism shift toward glutaminolysis with α‐ketoglutarate as a regulator of Tfh subset polarization. Glutaminolysis is required for DC allergen uptake, co‐stimulatory molecule expression, and CLR expression. Modulation of glutaminolysis, JmjD3 histone demethylation, or HIF‐1α degradation alters Tfh polarization and ...

IgE‐Binding Bacterial Components Not Yet Documented in the Allergen Databases and Their Allergenic Mechanisms: An EAACI Position Paper

Allergy, EarlyView.
ABSTRACT Among bacteria that are associated with the development and/or exacerbation of allergic/atopic diseases, several have been described to produce IgE‐binding components. However, only one bacterial protein, Bac s 1, is currently listed in the official database of the World Health Organization/International Union of Immunological Societies (WHO ...

ZAN, IZUMO1, and TMEM95 Protein Domains Identify the Physiological Status of the Sperm

Andrology, EarlyView.
ABSTRACT Background Infertility is a growing concern, which has led to an increase in the use of assisted reproductive techniques, involving in vitro sperm capacitation. Nonetheless, the optimal capacitation time remains a matter of debate, and it is unknown whether it has an impact on the localization of key membrane proteins.

Male Mice Heterozygous for Protamine 1 and Protamine 2 Are Infertile, Displaying Sperm Damage and Retention of Protamine 2 Precursors, Transition Proteins, and Histones

Andrology, EarlyView.
ABSTRACT Background During spermiogenesis, protamines (PRMs) replace histones to hypercondense and protect sperm DNA. Rodents and primates express two PRMs (PRM1 and PRM2). Alterations of species‐specific PRM ratios are associated with sub‐ or infertility in mice and humans.

Lactate‐Responsive Glycogen Dynamics Are Associated With Bull Sperm Motility and Fertilization Under Glucose‐Limited Conditions

Andrology, EarlyView.
ABSTRACT Background Mammalian sperm need to undergo hyperactivation, capacitation, and acrosome reaction to achieve fertilization competence. However, the female reproductive tract presents contrasting metabolic environments. The uterus is glucose‐rich, and the oviduct is lactate‐rich and glucose‐limited.

Morphological and Morphometric Characterisation of Selected Camarodont Sea Urchin (Echinoidea: Camarodonta) Pedicellariae (Paracentrotus lividus, Psammechinus miliaris and Echinus esculentus)

Acta Zoologica, EarlyView.
ABSTRACT Pedicellariae are small appendages on the surface of the echinoid test, involved in defence, cleaning, and locomotion. Pedicellariae in three species of camarodont sea urchins common in UK waters (Paracentrotus lividus [Lamarck, 1816], Psammechinus miliaris [P.L.S Müller, 1771] and Echinus esculentus [Linnaeus, 1758]) are the focus of this ...

The immunological landscape of the area postrema in neuromyelitis optica spectrum disorders

Brain Pathology, EarlyView.
Aquaporin‐4 antibody‐positive neuromyelitis spectrum disorder is characterized by large tissue destructive lesions in medulla, spinal cord, and optic nerves, with only partial recovery from clinical symptoms, and by lesions with very little tissue destruction and mostly complete recovery from clinical symptoms, as seen in the area postrema ...

Protective role of Galectin‐3 in prion disease through regulation of microglial PrPSc uptake

Brain Pathology, EarlyView.
Galectin‐3 (Gal3) is induced in reactive microglia during prion disease and promotes microglial uptake of PrPSc. Gal3 deficiency reduces prion sequestration and accelerates disease progression, revealing a protective role for Gal3. Abstract Microglia constitute a major innate defense mechanism against prion infection; however, the molecular pathways ...

Therapeutic potential of natural products in cancer immunotherapy: Advances and challenges

British Journal of Pharmacology, EarlyView.
This review systematically outlines the mechanisms underlying tumour immunotherapy resistance and elucidates the role of natural products in enhancing therapeutic efficacy as immunomodulatory adjuvants. Abstract Immunotherapy has emerged as a clinically pivotal approach in cancer treatment, but its application remains limited to a small subset of ...

Targeting KRAS for cancer therapy

British Journal of Pharmacology, EarlyView.
In recent years, therapeutics targeted against KRAS proto‐oncogene GTPase (KRAS)‐mutant cancers have seen significant progress. Herein we outline the biology and epidemiology of KRAS alterations at the lineage and allele levels, reviewing the clinical evidence for KRASG12C inhibition from the discovery of the recessive switch pocket to sotorasib ...
