Treg cells retain stable lineage commitment during pregnancy in mice after late gestation inflammatory challenge

Immunology &Cell Biology, Volume 104, Issue 3, Page 276-311, March 2026.
In this study, we used Foxp3‐fatemapping mice to examine the cell lineage stability of Treg cells in pregnancy. Ex‐Foxp3 cells were identified in gestational tissues. However, Treg cells retained lineage stability with no increased ex‐Foxp3 generation, regardless of inflammatory challenges that induce preterm birth.

Effect of two low doses of prostaglandin F_2α on luteolysis in dairy cows [PDF]

, 2017
In this preliminary study, we determined the effect of a modified method involving the administration of two low doses of prostaglandin F2α (PGF2α) at an interval of 24 h on luteolysis in dairy cows, and compared it with the standard single-dose method ...

Effect of Flushing Diets With Different Omega‐6 to Omega‐3 Fatty Acids Ratios on Reproductive Performance and Blood Biochemical Attributes in Shall Ewes

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
Dietary supplementation with different omega‐6:omega‐3 fatty acid ratios influenced ovarian activity, reproductive hormones and fertility outcomes in Shall ewes under semiarid conditions. Ewes receiving the lower ω6:ω3 ratio (1.5) showed improved follicular dynamics, higher progesterone levels and enhanced conception rate compared with higher ratios ...

Short communication: Heat stress does not affect induced luteolysis in Holstein cows [PDF]

, 2020
Heat stress (HS) has deleterious effects on bovine reproduction, including prolongation of the luteal phase in Holstein cows, perhaps due to compromised luteolysis.

Efficacy of Supplementary Guanidinoacetic Acid at Different Dietary Crude Protein Levels on the Productive Performance, Egg Quality, Intestinal Morphology, Antioxidative Status, and Serum Metabolites of Aged Laying Hens Exposed to High Ambient Temperatures

Veterinary Medicine and Science, Volume 12, Issue 1, January 2026.
0.15% GAA supplementation enhanced body weight and productive performance in heat‐stressed aged hens. Serum creatine, nitric oxide, and antioxidant capacity increased with GAA, while egg quality remained unaffected. One percent reduced protein diet with GAA maintained performance, whereas 2% reduction caused losses.

Antimicrobial prescribing guidelines for horses in Australia

Australian Veterinary Journal, Volume 103, Issue 12, Page 781-889, December 2025.
The growing problem of antimicrobial resistance also affects equine veterinarians with increasing frequency. Antimicrobial stewardship and responsible prescribing are essential for a future in which effective antimicrobials are available, as it is unlikely that new antimicrobials will become available for use in horses.

Loss of luteotropic prostaglandin E plays an important role in the regulation of luteolysis in women [PDF]

, 2017
STUDY QUESTION: Do intraluteal prostaglandins (PG) contribute to luteal regulation in women? SUMMARY ANSWER: Prostaglandin E (PGE), which is produced in human granulosa-lutein cells stimulated with luteotropic hCG, exerts similar luteotropic effects to ...

Specific effects on the reproductive function including fertility relevant for cumulative risk assessment of pesticide residues

EFSA Journal, Volume 23, Issue 12, December 2025.
Abstract According to the ‘EFSA‐SANTE Action Plan on Cumulative Risk Assessment for pesticides residues’, EFSA, with the support of a working group, undertook the identification of specific effects on male and female reproductive function, including fertility, that are considered relevant for grouping pesticide residues and for assessing ...

Luteal function and follicular growth following follicular aspiration during the peri-luteolysis period in bos indicus and crossbred cattle [PDF]

, 2012
Follicular estradiol triggers luteolysis in cattle. Therefore, the control of follicle growth and steroidogenesis is expected to modulate luteal function and might be used as an anti-luteolytic strategy to improve embryo survival.

Disruption of ovarian function and induction of apoptosis in female mice by Brefeldin A: Mechanistic insights into reproductive toxicity

Animal Models and Experimental Medicine, Volume 8, Issue 11, Page 2053-2068, November 2025.
Brefeldin A (BFA) significantly inhibits oocyte release and induces apoptosis in ovarian granulosa cells by disrupting follicular development. It downregulates proliferation‐associated genes, reduces SIRT1/SIRT6 proteins, and upregulates cell cycle inhibitors P21 and P16. Additionally, BFA impairs estrogen synthesis and affects ovarian function through
