Hesperidin produces antidepressant effects by activating AMPA receptor: enhancing synaptic proteins to promote hippocampal neuronal activities.

Hesperidin treatments reduce depressive symptoms in mouse models of depression, but the mechanism that mediates its antidepressant effects is unclear. This study shows that hesperidin exerts its antidepressant effects by activating α-amino-3-hydroxy-5-methyl-4-isoxazole-propionic acid (AMPA) receptor to promote synaptic and neuronal function in the hippocampus. The optimal dose of hesperidin (10 mg/kg) for the antidepressant potential was determined after 7 consecutive days of treatments, demonstrating decreased latency to eat and increased food consumption in novelty suppressed feeding, and decreased immobility time in tail suspension test (TST).

Berberine in combination with evodiamine ameliorates gastroesophageal reflux disease through TAS2R38/TRPV1-mediated regulation of MAPK/NF-κB signaling pathways and macrophage polarization.

Triggered Cascade-Activation Nanoplatform to Alleviate Hypoxia for Effective Tumor Immunotherapy Guided by NIR-II Imaging.

Hypoxia is one of the most typical features among various types of solid tumors, which creates an immunosuppressive tumor microenvironment (TME) and limits the efficacy of cancer treatment. Alleviating hypoxia becomes a key strategy to reshape hypoxic TME which improves cancer immunotherapy. However, it remains challenging to perform tumor precision therapy with controllable switches through hypoxia-activated gene editing and prodrugs to alleviate hypoxia.

Puerarin ameliorates colitis by direct suppression of macrophage M1 polarization in DSS mice.

Background: Ulcerative colitis (UC) is a type of inflammatory bowel disease primarily affecting the colon and rectum. The clinical symptoms of UC include persistent diarrhea, abdominal pain, and rectal bleeding, with chronic inflammation often limited to the mucosal layer of the colon. Macrophages play a significant role in the pathogenesis of UC in response to the presence of gut microbiota.

Emerging trends and research hotspots in the relationship between mast cells and atopic dermatitis based on the literature from 2001 to 2024: A bibliometric and visualized analysis.

Background: Atopic dermatitis (AD) is a prevalent chronic inflammatory and highly pruritic skin condition characterized by the infiltration of immune cells, notably eosinophils and mast cells. Mast cells (MCs) critically participate in the complex pathogenesis of AD through multiple pathways and have recently garnered growing attention in research. Despite the abundance of related studies published over the years, a comprehensive bibliometric analysis on this topic remains lacking.

Mammary hydroxylated oestrogen activates the NLRP3 inflammasome in tumor-associated macrophages to promote breast cancer progression and metastasis.

Breast cancer remains one of the primary causes of cancer-related death. An imbalance of oestrogen homeostasis and an inflammatory tumor microenvironment (TME) are vital risk factors for the progression and metastasis of breast cancer. Here, we showed that oestrogen homeostasis was disrupted both in breast cancer patients and in a transgenic MMTV-PyMT mouse model of breast cancer, and significant levels of hydroxylated oestrogen accumulated in the mammary tissues of these patients and mice.
