Blood Protozoan Infection Disrupts Ovarian Follicular Development in Dairy Cattle: A Mechanistic Link to Reproductive Failure

Veterinary Medicine and Science, Volume 12, Issue 4, July 2026.
Subclinical haemoprotozoan infection disrupts RBC integrity, and that leads to decreased Hb level and excess free iron in plasma. That subsequently impairs ovarian follicular development and thereby builds up a mechanistic link to reproductive failure in dairy cattle.

Proteomic and Transcriptomic Signatures of Poor Asthma Symptom Control in the U‐BIOPRED Cohort

Allergy, Volume 81, Issue 7, Page 2366-2380, July 2026.
No stable features were identified as associated with asthma symptom control in transcriptomics or sputum proteomics. Higher TWEAKR/TNFRSF12A and MBL/MBP‐C serum levels increased the odds of uncontrolled symptoms, while higher MK08/MAPK8 and CD5L serum levels decreased the odds, after adjustment for clinical variables.

Cytosolic delivery of bacterial metabolites by riboflavin transporters promotes MR1 antigen presentation and MAIT cell recognition

Immunology &Cell Biology, Volume 104, Issue 6, Page 595-608, July 2026.
VitBAg antigen presentation is promoted through a cytosolic pathway that reaches ligand‐receptive MR1 to present to MAIT cells, like the riboflavin transport pathway. Riboflavin solute carrier transporters can promote this MR1 presentation, but they are not essential for this role, suggesting redundant pathways to uptake VitBAg.

Identification of Distinct Interacting Proteins of Giardia lamblia Centrins Using Yeast Two‐Hybrid Assays

Journal of Eukaryotic Microbiology, Volume 73, Issue 4, July/August 2026.
ABSTRACT Giardia lamblia, a protozoan parasite that causes diarrhea in humans, contains two centrins implicated in cellular morphology and cell division. To identify proteins interacting with each G. lamblia centrin (GlCent), we performed a yeast two‐hybrid assay.
