Cytokines like IL-6, TNF-α, and IL-1β are important mediators of inflammation in many inflammatory diseases, as well as in cellular processes like cell proliferation and cell adhesion. Finding new molecules that decrease cell proliferation, adhesion (inflammatory infiltrate), and pro-inflammatory cytokine release could help in the treatment of many inflammatory diseases. The naturally derived poly(gallic acid) (PGAL), produced enzymatically from gallic acid in aqueous medium, is a non-toxic, thermostable multiradical polyanion that is antioxidant and has potential biomedical uses. Experimental evidence has demonstrated that PGAL reduces pro-inflammatory cytokines, which are the target of some inflammatory diseases. PGAL decreased IL-6, TNF-α, and IL-1β production in human monocytes exposed to PMA without affecting cell viability. Additionally, PGAL reduced cell proliferation by affecting the transition from the S phase to the G2 phase of the cell cycle. Cell adhesion experiments showed that PMA-induced cell adhesion was diminished with the presence of PGAL, particularly at a concentration of 200 μg/mL. These properties of PGAL show a potential use for treating inflammatory diseases, such as psoriasis or arthritis.

Abstract Background There is growing evidence of the ability of microRNAs (miRs) in rheumatoid arthritis (RA), thus our objective was to discuss the impact of miR-365 on the apoptosis and proliferation of synoviocytes in mice with RA by targeting IGF1 and mediating the PI3K/AKT/mTOR pathway. Methods RA model mice was induced by type II collagen and freund’s adjuvant. The successfully modeled mice were injected with normal saline, miR-365 mimics, miR-365 inhibitors or their controls. TUNEL assay ...

: Modulation of the immune system has gathered more attention in the field of medicine due to the immense potential that it presents. Our immune system has important roles against cancer to infectious diseases, as well as in the development of autoimmune disorders. Therefore, being able to manipulate our immune system cells would enable us to determine the type and strength of the immune response to certain danger stimuli. Macrophages play an important role in the regulation of the immune system...

Abstract Our study aimed to determine the effects of sodium tanshinone IIA sulfonate (STS) on proliferation, migration, invasion, and inflammation in rheumatoid arthritis human fibroblast-like synoviocytes (RA-HFLSs). Firstly, results demonstrated STS reduced proliferation, migration, invasion in HFLSs. Also, we found that STS could alleviate the reorganizations of F-actin cytoskeleton in TNF-α-treated HFLSs. In addition, STS decreased the production of IL-1β, IL-6, MMP-1, and MMP-3 in TNF-α-tre...

Abstract Gallic acid (GA), a natural small molecule found in Radix Paeoniae Rubra, has a variety of favorable biological activities. However, the anti-psoriasis effect of GA has never been explored up to now. This study evaluates the protective effect of GA on psoriasis-like skin disease both in vitro and in vivo and explores the underlying mechanism. The results show that GA significantly decreases the mRNA and protein expression of keratin 16 and keratin 17 which are the markers of psoriasis. ...

: Autoimmune disorders are a category of diseases in which the immune system attacks healthy cells as a result of a dysfunction of the acquired immune system. Clinical presentation and diagnosis are disease specific and often correspond with the degree of inflammation, as well as the systems involved. Treatment varies based on the specific disease, its stage of presentation, and patient symptoms. The primary goal of treatment is to decrease inflammation, minimize symptoms, and lessen the potenti...

Abstract There are numerous extra- and intra-cellular processes involved in the production of reactive oxygen species (ROS). Augmented ROS generation can cause the damage of biomolecules such as proteins, nucleic acid and lipids. ROS act as an intracellular signaling component and is associated with various inflammatory responses, chronic arthropathies, including rheumatoid arthritis (RA). It is well documented that ROS can activate different signaling pathways having a vital importance in the p...

Abstract Background Fluoxetine-induced liver damage is a cause of chronic liver disease. In the present study the hepatoprotective effects of gallic acid against fluoxetine-induced liver damage were examined. Methods Forty-eight male rats were divided into six groups as follow: group 1, the control group; group 2, rats receiving fluoxetine (24 mg/kg bw daily, po ) without treatment; group 3, rats receiving 24 mg/kg bw fluoxetine, treated with 50 mg/kg bw silymarin and groups 4, 5, and 6 in which...

Abstract The poly(gallic acid), produced by laccase-mediated oxidation of gallic acid in aqueous media (pH 5.5) to attain a novel material with well-defined molecular structure and high water solubility (500 mg/mL at 25 °C), has been investigated to understand its potential biological activities. In this regard, a biomedical approach based on cytoprotective effect on human fibroblast cells exposed to UV-irradiation in the presence of the polymer has been demonstrated. The results also shows that...

Background Punica granatum (pomegranate), an edible fruit originating in the Middle East, has been used as a traditional medicine for treatment of pain and inflammatory conditions such as peptic ulcer. The numerous risks associated with nonsteroidal anti-inflammatory drugs (NSAIDs) for treatment of pain and inflammation give rise to using medicinal herbs as alternative therapies. This study aimed to evaluate the anti-inflammatory effect of isolated compounds from the ethyl acetate (EtOAc) fracti...

Abstract Rheumatoid arthritis (RA) is one of the most common autoimmune diseases and is characterized by synovitis that causes joint damage. The introduction of biologic agents has made it possible to induce remission in many patients and inhibit joint damage. Activated T cells in RA patients proliferate and stimulate the production of pro-inflammatory cytokines including tumor necrosis factor (TNF) and interleukin 6 that play important roles in RA pathogenesis. The most widely used biologic age...

The COVID-19 pandemic has caused a global health crisis, with no specific antiviral to treat the infection and the absence of a suitable vaccine to prevent it. While some individuals contracting the SARS-CoV-2 infection exhibit a well coordinated immune response and recover, others display a dysfunctional immune response leading to serious complications including ARDS, sepsis, MOF; associated with morbidity and mortality. Studies revealed that in patients with a dysfunctional immune response, th...
