Structure of PD1 and its mechanism in the treatment of autoimmune diseases.

PD-1 and CTLA-4 can play an important role in addressing the issue of autoimmune diseases. PD-1 is a transmembrane glycoprotein expressed on T, B, and Dentric cells. This molecule functions as a checkpoint in T cell proliferation.

STA-21, a small molecule STAT3 inhibitor, ameliorates experimental autoimmune encephalomyelitis by altering Th-17/Treg balance.

Background: Numerous studies have demonstrated the role of T helper (Th) 17 and T regulatory (reg) cells and pro-inflammatory and anti-inflammatory cytokines related to these cells in the pathogenesis of MS and its animal model, experimental autoimmune encephalomyelitis (EAE). STAT3 is one of the downstream signaling proteins of IL-23, IL-6, and IL-21 that are required for Th17 cells differentiation. STA-21 is a STAT3 inhibitor that functions by inhibiting STAT3 dimerization and binding to DNA impairing the expression of STAT3 target genes including, RORγt, IL-21 and IL-23R that are also required for Th17 cell differentiation.

Comprehensive comparison of theranostic nanoparticles in breast cancer.

Breast cancer is the most frequently happening cancer and the most typical cancer death among females. Despite the crucial progress in breast cancer therapy by using Chemotherapeutic agents, most anti-tumor drugs are insufficient to destroy exactly the breast cancer cells. The noble method of drug delivery using nanoparticles presents a great promise in treating breast cancer most sufficiently and with the least harm to the patient.

Under hypoxic conditions, MSCs affect the expression and methylation level of survival-related genes in ALL independent of apoptosis pathways in vitro.

Mesenchymal stem cells (MSCs) are one of the most prominent cells in the bone marrow. MSCs can affect acute lymphocytic leukemia (ALL) cells under hypoxic conditions. With this aim, we used MOLT-4 cells as simulators of ALL cells cocultured with bone marrow mesenchymal stem cells (BMMSCs) under hypoxic conditions in vitro.

Ruxolitinib attenuates experimental autoimmune encephalomyelitis (EAE) development as animal models of multiple sclerosis (MS).

Main Methods: Ruxolitinib was administered to experimental autoimmune encephalomyelitis (EAE) mice via oral gavage, and its effects were assessed.

miR-193a-5p as a promising therapeutic candidate in colorectal cancer by reducing 5-FU and Oxaliplatin chemoresistance by targeting CXCR4.

Colorectal cancer (CRC) is one of the most common causes of cancer-related deaths worldwide. The role of microRNAs (miRNAs/miRs) as small (19-25 nucleotides in length) non-coding RNA molecules that modify gene expression has been shown in several types of cancer. 5-Fluorouracil (5-FU) and oxaliplatin (Ox) are two common chemotherapeutic agents used to treat cancer.

Epigenetic mechanisms shape the underlining expression regulatory mechanisms of the STAT3 in multiple sclerosis disease.

Objectives: Immunological tolerance is mediated by CD4CD25 regulatory T (Treg) cells. Studies have shown that thymic and peripheral generations of Treg cells depend on the CD28 signaling pathway. T helper 17 (Th17) cells are involved in the pathophysiology of various inflammatory diseases.

Innate and adaptive immune responses against coronavirus.

Coronaviruses (CoVs) are a member of the Coronaviridae family with positive-sense single- stranded RNA. In recent years, the CoVs have become a global problem to public health. The immune responses (innate and adaptive immunity) are essential for elimination and clearance of CoVs infections, however, uncontrolled immune responses can result in aggravating acute lung injury and significant immunopathology.

Targeting STAT3 in cancer and autoimmune diseases.

Signal transducer and activator of transcription 3 (STAT3) is a transcription factor that is activated downstream of a broad range of receptors particularly interleukin-6 (IL-6) family. STAT3 is the key regulator of cell proliferation, survival and apoptosis and is constitutively activated in most human cancers, indicating that it can be an important potential therapeutic target for cancer treatment. STAT3 also has important roles in lymphocyte biology, regulation of immune responses and autoimmunity.

The role of B cells in the immunopathogenesis of multiple sclerosis.

There is ongoing debate on how B cells contribute to the pathogenesis of multiple sclerosis (MS). The success of B-cell targeting therapies in MS highlighted the role of B cells, particularly the antibody-independent functions of these cells such as antigen presentation to T cells and modulation of the function of T cells and myeloid cells by secreting pathogenic and/or protective cytokines in the central nervous system. Here, we discuss the role of different antibody-dependent and antibody-independent functions of B cells in MS disease activity and progression proposing new therapeutic strategies for the optimization of B-cell targeting treatments.

Janus kinase inhibitors: A therapeutic strategy for cancer and autoimmune diseases.

Many cytokines are crucial drivers of cancers and autoimmune conditions. These proteins bind to receptors and signal their responses through Janus kinase (JAK) and signal transducer and activator of transcription (STAT) pathways. Genetic variations in the JAK-STAT pathway are correlated with the increased risk of cancers, autoimmunity as well as inflammatory diseases.

CTLA-4: From mechanism to autoimmune therapy.

CD28 and CTLA-4 are both important stimulatory receptors for the regulation of T cell activation. Because receptors share common ligands, B7.1 and B7.

IL-21 and IL-21-producing T cells are involved in multiple sclerosis severity and progression.

Multiple sclerosis is a common neuroinflammatory disease of the central nervous system causing nervous system defects and severe physical disability. IL-21 is a proinflammatory cytokine produced mainly by Th-17 and Tfh cells which its exact role in MS was not yet clearly understood. In the present study we aimed to investigate the possible correlation of IL-21 gene expression, methylation, and its serum levels with MS severity and progression.

Dimethyl fumarate: Regulatory effects on the immune system in the treatment of multiple sclerosis.

Dimethyl fumarate (DMF) is an important oral treatment option for various autoimmune diseases, such as multiple sclerosis (MS) and psoriasis. DMF and its dynamic metabolite, monomethyl fumarate (MMF) are the major compounds that exert therapeutic effects on several pathologic conditions in part, through downregulation of immune responses. The exact mechanism of DMF is yet to be fully understood even though its beneficial effects on the immune system are extensively studied.

Curcumin modulates the angiogenic potential of human endothelial cells via FAK/P-38 MAPK signaling pathway.

Many phyto-compounds are found to have anti-angiogenesis property. Curcumin, a natural polyphenol, has been used as medicinal plant for years with different biological activities. Here, we investigated the effect of curcumin on angiogenesis potential of human endothelial cells.

Polymorphism of Foxp3 gene affects the frequency of regulatory T cells and disease activity in patients with rheumatoid arthritis in Iranian population.

Rheumatoid arthritis (RA) is a chronic autoimmune disease that mainly affects joints and characterized by chronic joint inflammation and infiltration of various immune cells in the synovium. Forkhead box P3 (Foxp3)-expressing regulatory T cells (Tregs) play a crucial role in preventing autoimmunity and undesirable T cell responses. However, there are controversial reports regarding the defective function or frequency of these cells in various studies, which may be in part related to different polymorphisms of FoxP3 and influence of ethnicity on these differences.
