Impaired microglia fractalkine signaling affects stress reaction and coping style in mice.
Zsuzsanna Winkler,Dániel Kuti,Szilamér Ferenczi,Krisztina Gulyás,Ágnes Polyák,Krisztina J. Kovács +5 more
TL;DR: Differential involvement of microglia fractalkine signaling in controlling/integrating hormonal‐, metabolic and behavioral responses to acute and chronic stress challenges is highlighted.

The fractalkine/Cx3CR1 system is implicated in the development of metabolic visceral adipose tissue inflammation in obesity.
Ágnes Polyák,Szilamér Ferenczi,Adam Denes,Zsuzsanna Winkler,Rókus Kriszt,Bernadett Pintér-Kübler,Krisztina J. Kovács +6 more
TL;DR: The effect of fat-enriched diet on cytokine expression pattern was specific for the WAT, as it did not detect significant elevation of interleukin-1, tumor necrosis factor-alpha and monocyte chemotacting protein expression in the liver or in the hypothalamus in either genotype.
Xenoestrogens Ethinyl Estradiol and Zearalenone Cause Precocious Puberty in Female Rats via Central Kisspeptin Signaling
Rókus Kriszt,Rókus Kriszt,Zsuzsanna Winkler,Zsuzsanna Winkler,Ágnes Polyák,Dániel Kuti,Dániel Kuti,Csilla S. Molnár,Erik Hrabovszky,Imre Kalló,Zsuzsanna Szőke,Szilamér Ferenczi,Krisztina J. Kovács +12 more
TL;DR: Both ZEA and EE2 accelerated the vaginal opening, increased the uterine weight and the number of antral follicles in the ovary, and resulted in the increased central expression of gnrh, compatible with a mechanism in which xenoestrogens overstimulate the developmentally unprepared reproductive system.
Wild Strawberry, Blackberry, and Blueberry Leaf Extracts Alleviate Starch-Induced Hyperglycemia in Prediabetic and Diabetic Mice

TL;DR: Berry leaf extracts inhibit α-glucosidase and α-amylase enzyme activity in vitro and are effective in preventing postprandial hyperglycemia in vivo, and are highlighted as candidates for testing in clinical trials to assess the clinical significance of their effects on glycemic control.
Brown adipose tissue in obesity: Fractalkine-receptor dependent immune cell recruitment affects metabolic-related gene expression.
TL;DR: The results highlight the importance of fractalkine-CX3CR1 interaction in recruitment of macrophages into the BAT of obese mice which might contribute to local tissue inflammation, adipose tissue remodeling and regulation of metabolic-related genes.
