NOD-like receptor family pyrin domain containing 3 (NLRP3) is an intracellular receptor that senses foreign pathogens and endogenous danger signals. It assembles with apoptosis-associated speck-like protein containing a CARD (ASC) and caspase-1 to form a multimeric protein called the NLRP3 inflammasome. Among its various functions, the NLRP3 inflammasome can induce the release of the pro-inflammatory cytokines interleukin (IL)-1β and IL-18 while also promoting gasdermin D (GSDMD)-mediated pyroptosis. Previous studies have established a vital role for the NLRP3 inflammasome in innate and adaptive immune system as well as its contribution to several autoimmune diseases including rheumatoid arthritis (RA), systemic lupus erythematosus (SLE), Sjögren's syndrome (SS), systemic sclerosis (SSc), and ankylosing spondylitis (AS). In this review, we briefly introduce the biological features of the NLRP3 inflammasome and present the mechanisms underlying its activation and regulation. We also summarize recent studies that have reported on the roles of NLRP3 inflammasome in the immune system and several autoimmune diseases, with a focus on therapeutic and clinical applications.
De novo lipogenesis (DNL) has been reported to involve in a serial types of disease. A standard triple therapy, including a PPI, omeprazole, and antibiotics (clarithromycin and amoxicillin), is widely used as the first-line regimen for helicobacter pylori (H. pylori)-infectious treatment. The objective of this study is to explore the function of a standard triple therapy on DNL.
We collected the clinical sample from the patients diagnosed with or without H. pylori infection. Oil red staining, real-time PCR, western blotting (WB) and adipored experiment were performed to detect the effect of a standard triple therapy on DNL. The expression of relative key enzymes was assessed in gastric mucosa of clinical sample by IHC. Both 54 cases with H. pylori-negative and 37 cases with H. pylori-positive were enrolled in this study, and IHC assay showed that both fatty acid synthase (FASN) and ATP-citrate lyase (ACLY) expression, the critical enzymes involved in DNL, were increased in gastric mucosa of patients with H. pylori-positive compared with that with H. pylori-negative. Real-time PCR and WB analysis showed that neither clarithromycin nor amoxicillin inhibited FASN and ACLY expression, while treatment of BGC823 cells with omeprazole with 200 μM or 300 μM significantly abolished FASN and ACLY expression, leading to reduce lipid content.
These findings suggested that omeprazole suppressed DNL in gastric cells, implying that targeting DNL is an alternative strategy in improving the treatment of patients with H. pylori infection.

Intimate partners and other informal caregivers provide unpaid tangible, emotional, and decision-making support for patients with cancer, but relatively little research has investigated the cancer experiences of sexual minority women (SMW) with cancer and their partners/caregivers.
This review addressed 4 central questions 1) What social support do SMW with cancer receive from partners/caregivers? 2) What effect does cancer have on intimate partnerships or caregiving relationships of SMW with cancer? 3) What effects does cancer have on partners/caregivers of SMW with cancer? 4) What interventions exist to support partners/caregivers of SMW or to strengthen the patient-caregiver relationship?
This systematic review, conducted in 2018 and updated in 2020, was based on Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Two independent coders screened abstracts and articles.
In total, 550 unique records were screened; 42 articles were assessed for eligibility, and 18 were inclusamples. Longitudinal research will allow an examination of patterns of mutual influence and change in relationships. These steps will enable the development of interventions to support SMW with cancer and people close to them.
More work is needed to understand SMW with cancers other than breast cancer, and future work should include more racially, ethnically, and economically diverse samples. Longitudinal research will allow an examination of patterns of mutual influence and change in relationships. These steps will enable the development of interventions to support SMW with cancer and people close to them.Wilson's disease is an inherited disorder associated with copper accumulation in the liver, brain and other vital organs. Wilson's disease is caused by mutations in the ATP7B gene. Over 300 mutations of ATP7B have been described. Despite the disease is autosomal recessive, the patient whose PBMCs were reprogrammed in the study harbours heterozygous mutation c.3207C > A (p.H1069Q). Detailed analysis of the ATP7B complete gene sequencing data has not revealed other known disease associated mutation. The generated iPSC lines maintained the original genotype, expressed pluripotency markers, had normal karyotype and demonstrated the ability to differentiate into derivatives of the three germ layers.Skeletal muscle has a capacity for muscular regeneration mediated by satellite cells (SCs) and non-SCs. Although it is proposed that non-SCs are attractive therapeutic targets for dystrophies, the biological properties of these cells remain unclear. We have recently identified novel multipotent pericytes (PCs), capillary stem cells (CapSCs) derived from the microvasculature. In the present study, we determined if CapSCs contributed to myogenic regeneration using muscular dystrophy mouse model. CapSCs were isolated as EphA7+NG2+PCs from the subcutaneous adipose tissues of GFP-transgenic mice. Co-culture with C2C12 myoblast cells showed that CapSCs effectively enhanced myogenesis as compared to controls including EphA7- PCs and adipose stromal cells (ASCs). check details CapSCs transplanted in cardiotoxin-injured gastrocnemius muscles were well differentiated into both muscle fibers and microvessels, as compared to controls. At three weeks after cell-transplantation into the limbs of the mdx/utrn-/-mouse, CapSCs increased the number of GFP+myofibers along with dystrophin expression and the area size of myofibers, and also enhanced the muscular mass and its performance, assessed by treadmill test as compared to controls.
