Iflaviruses in arthropods: when small is mighty

Insect Science, EarlyView.
Many arthropod species harbor iflaviruses, which often cause covert (asymptomatic) infections, but may still affect host fitness. We review the impact of iflaviruses on arthropod fitness, immunity, behaviour as well as the iflavirus’ host range, transmission, tissue tropism and the interactions with other microorganisms within arthropods.

Effects of Salicylic Acid Application on Pollen Viability and Germination of Date Palm (Phoenix dactylifera L.) under Heat and Cold Stress

Notulae Botanicae Horti Agrobotanici Cluj-Napoca
Date palm (Phoenix dactylifera L.) reproductive success is highly vulnerable to temperature fluctuations, which impair pollen viability and germination. This study investigated whether exogenous salicylic acid (SA) enhances pollen performance under heat

Kinetics of Antibody Responses and Effector Cell Sensitivity After High Dose Birch Extract Nasal Challenge

Allergy, EarlyView.
High‐dose birch‐extract nasal challenge induced synchronous peaks at 4 weeks in serum specific IgE (sIgE) and basophil sensitivity. Mast cell sensitivity via tSPT and sIgG1 and sIgG4 responses peaked later, at 6–8 weeks. Preseasonal allergen exposure attenuated seasonal sIgE increase and prevented further rise in tSPT sensitivity.

Serotonin Degradation and Lipid Metabolism Regulate Human Tc2 Cell Effector Functions

Allergy, EarlyView.
Human Tc2 cells exhibit a metabolically active phenotype characterized by enhanced glycolysis, mitochondrial respiration, and fatty acid uptake dependent on PPARγ. Alarmins strongly amplify IL‐5 and IL‐13 production in Tc2 cells, supporting a shared immunometabolic program across type 2 lymphocytes.

Deficiency of Mitochondrial Fatty Acid Enzyme, CPT1A, Underlies Airway Epithelial Barrier Dysfunction in Severe Asthma

Allergy, EarlyView.
Mitochondrial fatty acid enzyme, CPT1A, is deficient in the airway epithelium of severe asthma patients. Restoration of CPT1A expression improved epithelial barrier integrity via increasing mitochondrial respiration and ATP production in airway epithelial cells. Restoration of deficient epithelial CPT1A may represent a new treatment approach for severe
