Multiple myeloma is a monoclonal postgerminal center tumor that has phenotypic features of plasmablasts and/or plasma cells and usually localizes at multiple sites in the bone marrow. The pathogenesis of multiple myeloma is complex and dependent on the interactions between tumor cells and their microenvironment. Different cytokines, chemokines, and proangiogenic factors released in the tumor mi...

Psoriasis is a chronic inflammatory disorder characterized by T cell dysregulation and a chronic inflammatory infiltrate within the epidermis. Several cytokines play an important role in the pathogenesis of psoriasis, including interleukin-12 (IL-12) and IL-23. These cytokines act via induction of pro-inflammatory cytokines which promote chronic inflammation and auto-reactivity. Ustekinumab is ...

Host defenses against Histoplasma capsulatum require the action of several cytokines. Here, we explored the influence of interleukin (IL)-17 and IL-23 on immunity to H. capsulatum infection in mice. In lungs, synthesis of IL-17 was up-regulated during acute infection, and the cells producing it were predominantly CD3(+). Neutralization of IL-17A blunted fungal clearance but did not promote prog...

INTRODUCTION Osteoarthritis (OA) is the most common type of arthritis and proinflammatory cytokines have been considered as the main etiologic factor in the pathogenesis of the disease. Serum levels of cytokines, that are associated with innate immunity and TH1 cells, have been analyzed in OA patients, however, there is limited research that profiles cytokines associated with Th17 cells and the...

Psoriatic arthritis is a chronic inflammatory autoimmune disease with varied manifestations, including functional limitation and reduced quality of life. Improved understanding the immunopathogenesis psoriatic arthritis, particularly role interleukin-23 interleukin-17 axis, has led to development therapeutic targets alter natural history condition. In this article, we review monoclonal antibodi...

There is an increasing amount of evidence supporting the hypothesis that the pathological stage from hepatitis to hepatocellular carcinoma (HCC) is a chronic inflammatory process. Interleukin‑23 (IL‑23) is an important mediator and modulator of inflammation. Specific polymorphisms in the genes encoding subunits of the IL‑23 receptor (IL‑23R) have been consistently observed to be associated with...

BP: Bullous pemphigoid TNF-a: tumor necrosis factor-alfa INTRODUCTION Ustekinumab, a monoclonal antibody that blocks interleukin-12 and interleukin-23, is a biological therapy used to treat moderate-to-severe psoriasis. Bullous pemphigoid (BP) induced by antietumor necrosis factor-alfa (TNF-a) agents has been described in the literature. No cases have been reported with ustekinumab. We report a...

Interleukin 23 receptor expressing IL-17 producing T cells have been shown to be important in the development of murine lupus. The usefulness of IL-23 inhibition in ameliorating lupus nephritis is unknown. We hypothesized that inhibition of IL-23 will ameliorate nephritis in lupus-prone mice. To this end, we treated MRL/lpr lupus-prone mice for 6 weeks with a rat anti-IL-23p19 antibody, which r...

The role of the interleukin (IL)23/IL17 axis in psoriasis is well-established and has led to development biologics targeting IL23 IL17A. Ustekinumab, targets IL12/23p40 shared subunit blocks IL23-receptor interactions, restricting activation Signal Transducer Activator Transcription 3 (STAT3) T cells, IL17A production. Secukinumab binding its receptor, preventing keratinocyte activation. Althou...
