Article Abstract
, a toxic Chinese medicine used for more than 2000 years, has the effect of "purging water to promote drinking" and "reducing swelling and dispersing modules". Diterpenes and triterpenes are the main bioactive components of . Among them, ingenane-type diterpenes have multiple biological activities as a protein kinase C δ (PKC-δ) activator, which have previously been shown to promote anti-proliferative and pro-apoptotic effects in several human cancer cell lines. However, the activation of PKC subsequently promoted the survival of macrophages. Recently, we found that 13-hydroxyingenol-3-(2,3-dimethylbutanoate)-13-dodecanoate (compound A) from showed dual bioactivity, including the inhibition of tumor-cell-line proliferation and regulation of macrophage polarization. This study identifies the possible mechanism of compound A in regulating the polarization state of macrophages, by regulating PKC-δ-extracellular signal regulated kinases (ERK) signaling pathways to exert anti-tumor immunity effects in vitro, which might provide a new treatment method from the perspective of immune cell regulation.

Radiation-induced skin injury (RSI) remains a significant clinical challenge due to persistent oxidative stress, chronic inflammation, and impaired tissue regeneration. It is demonstrated that RSI is accompanied by dysregulation of the immune microenvironment, wherein macrophages act as key regulators of all pathological cascades. Here, we developed a dual network hydrogel (Gel/SA@MXene) through dual cross-linking via UV irradiation and calcium ions to accelerate radiation-combined wound healing.

Background: Aristolochic acids (AA) are naturally occurring carcinogens found in traditional herbal medicines derived from Aristolochia species. This study explores the potential link between AA and hepatocellular carcinoma (HCC), aiming to uncover key molecular targets driving AA-induced hepatocarcinogenesis.
Methods: Toxicogenomic databases were used to identify AA-related toxicological profiles and targets, which were integrated with HCC-associated gene datasets.

Objective: Beta-hydroxybutyrate (BHB) has been demonstrated to enhance cardiac function in patients with diabetic cardiomyopathy (DCM), the underlying mechanism remains unclear.
Methods: A DCM rat model was established, BHB was administered via intraperitoneal injection. The therapeutic effects of BHB were assessed based on cardiac function, fasting glucose levels, myocardial fibrosis markers and myocardial macrophage polarization.

While human autopsy samples have provided insights into pulmonary immune mechanisms associated with severe viral respiratory diseases, the mechanisms that contribute to a clinically favorable resolution of viral respiratory infections remain unclear due to the lack of proper experimental systems. Using mice co-engrafted with a genetically matched human immune system and fetal lung xenograft (fLX), we mapped the immunological events defining successful resolution of SARS-CoV-2 infection in human lung tissues. Viral infection is rapidly cleared from fLX following a peak of viral replication, histopathological manifestations of lung disease and loss of AT2 program, as reported in human COVID-19 patients.
