Spatial multi‐omics unveils sphingolipid metabolic reprogramming within the retinal pathological niche

iMeta, EarlyView.
Spatial multi‐omics of the mouse ocular globe after retinal ischemia‐reperfusion (RIR) injury identifies the ganglion cell layer (GCL) as an immunometabolic niche where Trem2+ microglia closely associate with stressed retinal ganglion cells (RGCs) through Trem2‐Apoe signaling.

Graded traumatic brain injury severity differentially modulates microglial and astrocytic polarization states and response to minocycline

Neuroprotection, EarlyView.
Schematic diagram of the experimental design and key findings of traumatic brain injury (TBI) with varying severities. Mild, moderate, and severe TBI were induced in the right motor cortex of mice using the controlled cortical impact (CCI) method, with impact depths of 0.5, 1.0, and 2.0 mm, respectively. A subset of severe TBI mice received minocycline

The role of C5aR1-mediated hepatic macrophage efferocytosis in NASH

Scientific Reports
Abstract NAFLD has become the first major chronic liver disease in developed countries. 10-20% of NAFLD patients will progress to NASH, and up to 25% of NASH patients may develop cirrhosis within 10 years. Therefore, it is critical to find key factors that may treat this disease.

Role of the C5a/C5aR1 axis in bone cells

, 2023
The complement system is an important part of the innate immune system, which is activated by endogenous or exogenous pathogens. The main functions of the complement system are the direct destruction of pathogens and cellular components, opsonization and initiation of phagocytosis, and the induction of an inflammatory response.

Anaphylatoxin Receptors C3aR and C5aR1 Are Important Factors That Influence the Impact of Ethanol on the Adipose Secretome

Frontiers in Immunology, 2018
Background and aims: Chronic ethanol exposure results in inflammation in adipose tissue; this response is associated with activation of complement as well as the development of alcohol-related liver disease (ALD).

Deciphering diverse cell‐death patterns to predict the prognosis and potential therapy target of hepatocellular carcinoma patients

VIEW, EarlyView.
Abstract Ninety percent of all primary liver malignancies are hepatocellular carcinomas (HCC), making liver cancer the third most common cause of cancer‐associated mortality. Different patterns of programmed cell death (PCD) are crucial for the survival of tumors, and they might serve as a prognostic marker for HCC.

Blockade of C5aR1 resets M1 via gut microbiota-mediated PFKM stabilization in a TLR5-dependent manner

Cell Death and Disease
Targeting C5aR1 modulates the function of infiltrated immune cells including tumor-associated macrophages (TAMs). The gut microbiome plays a pivotal role in colorectal cancer (CRC) tumorigenesis and development through TAM education. However, whether and

Complement Activation in Association with Markers of Neutrophil Extracellular Traps and Acute Myocardial Infarction in Stable Coronary Artery Disease

Mediators of Inflammation, 2020
Complement activation and neutrophil extracellular traps (NETs) have both been suggested to drive atherosclerotic plaque progression. Although experimental studies suggest interplay between these two innate immunity components, the relevance in patients ...

Basophils in Immunity: Activation Pathways, Roles in Allergy and AllergoOncology and Application of the Basophil Activation Test

Allergy, EarlyView.
ABSTRACT Basophils, the least abundant leukocytes, are increasingly recognised as potent immunomodulators. Upon activation, they rapidly release preformed granule‐associated mediators including histamine and lipid mediators such as LTC4, while cytokine production occurs over a longer timescale, contributing to downstream immune responses.
