Recent studies emphasize the importance of low-density lipoprotein cholesterol (LDL-C) in altering the hematopoietic cell compartment of bone marrow and of high-density lipoprotein cholesterol (HDL-C) in inhibiting metabolic endotoxemia-induced inflammation. The data suggest that these lipoproteins may exert their inflammatory or anti-inflammatory roles by modulating innate immune memory. Targeting specific LDL-C and HDL-C subfractions could therefore potentially reduce the residual risk in hepatic and cardiometabolic disease.

Background: Adenosine deaminase action on RNA 1 (ADAR1) can convert the adenosine in double-stranded RNA (dsRNA) molecules into inosine in a process known as A-to-I RNA editing. ADAR1 regulates gene expression output by interacting with RNA and other proteins; plays important roles in development, including growth; and is linked to innate immunity, tumors, and central nervous system (CNS) diseases.
Results: In recent years, the role of ADAR1 in tumors has been widely discussed, but its role in CNS diseases has not been reviewed.

The complement system and neutrophils constitute the two main pillars of the host innate immune defense against infection by bacterial pathogens. Here, we identify T-Mac, a novel virulence factor of the periodontal pathogen Treponema denticola that allows bacteria to evade both defense systems. We show that T-Mac is expressed as a pre-protein that is cleaved into two functional units.

DNA damage in cells induces the expression of inflammatory genes. However, the mechanism by which cells initiate an innate immune response in the presence of DNA lesions blocking transcription remains unknown. Here we find that genotoxic stresses lead to an acute activation of the transcription factor NF-κB through two distinct pathways, each triggered by different types of DNA lesions and coordinated by either ataxia-telangiectasia mutated (ATM) or IRAK1 kinases.

Dietary Astragalus polysaccharides (APS) get wide application in aquaculture due to their excellent immunoregulatory effects. However, little is known about the effects of dietary APS on vaccine potency in fish. In the present study, large yellow croakers (Larimichthys crocea) were injected with formalin-inactivated Pseudomonas plecoglossicida after APS feeding for 14 d and then challenged by live P.

We have previously reported that high-alcohol-producing Klebsiella pneumoniae (HiAlc Kpn) in the gut can cause endo-alcoholic fatty liver disease. Here, we discover that 91.2% of Kpn isolates from pulmonary disease samples also produce excess ethanol, which may be associated with respiratory disease severity.
