Interleukin (IL)-32, mainly produced by T-lymphocytes, natural killer cells, epithelial cells, and blood monocytes, is dominantly known as a pro-inflammatory cytokine. However, the role of IL-32 on inflammatory disease has been doubtful according to diverse conflicting results. This study was designed to examine the role of IL-32β on the development of collagen antibody (CAIA) and lipopolysaccharide (LPS)-induced inflammatory arthritis. Our data showed that the paw swelling volume and clinical score were significantly reduced in the CAIA and LPS-treated IL-32β transgenic mice compared with non-transgenic mice. The populations of cytotoxic T, NK and dendritic cells was inhibited and NF-κB and STAT3 activities were significantly lowered in the CAIA and LPS-treated IL-32β transgenic mice. The expression of pro-inflammatory proteins was prevented in the paw tissues of CAIA and LPS-treated IL-32β transgenic mice. In addition, IL-32β altered several cytokine levels in the blood, spleen and paw joint. Our data indicates that IL-32β comprehensively inhibits the inflammation responses in the CAIA and LPS-induced inflammatory arthritis model.

Epithelial-to-mesenchymal transition (EMT) is a critical and complex process involved in normal embryonic development, tissue regeneration, and tumor progression. It also contributes to retinal diseases, such as age-related macular degeneration (AMD) and proliferative vitreoretinopathy (PVR). Although absent in melanoma 2 (AIM2) has been linked to inflammatory disorders, autoimmune diseases, and cancers, its role in the EMT of the retinal pigment epithelium (RPE-EMT) and retinal diseases remains unclear.

Neurons in the cerebral cortex and hippocampus discharge synchronously in brain state-dependent manner to transfer information. Published studies have highlighted the temporal coordination of neuronal activities between the hippocampus and a neocortical area, however, how the spatial extent of neocortical activity relates to hippocampal activity remains partially unknown. We imaged mesoscopic neocortical activity while recording hippocampal local field potentials in anesthetized and unanesthetized GCaMP-expressing transgenic mice.

Adenosine-to-inosine (A-to-I) editing, is a highly prevalent posttranscriptional modification of RNA, mediated by the adenosine deaminases acting on RNA (ADAR) proteins. Mammalian transcriptomes contain tens of thousands to millions of A-to-I editing events. Mutations in ADAR can result in rare autoinflammatory disorders such as Aicardi-Goutières syndrome (AGS) through to irreversible conditions such as motor neuron disease, amyotrophic lateral sclerosis (ALS).

Attention-Deficit/Hyperactivity Disorder (ADHD) is associated with an increased risk of Parkinson's disease (PD) and other synucleinopathies later in life. The severity of the ADHD phenotype may play a significant role in this association. There is no indication that any of the existing animal models can unify these disorders.

Objective: Aberrant 6-phosphofructo-2kinase/fructose-2,6-bisphoshatase 3 (PFKFB3) expression is tightly correlated with multiple steps of tumorigenesis; however, the pathological significance of PFKFB3 in macrophages in patients with rheumatoid arthritis (RA) remains obscure. In this study, we examined whether PFKFB3 modulates macrophage activation and promotes RA development.
Method: Peripheral blood mononuclear cells (PBMCs) from patients with RA, THP-1 cells, and bone marrow-derived macrophages from conditional PFKFB3-knockout mice were used to investigate the mechanism underlying PFKFB3-induced macrophage regulation of RA.
