Institute of Tropical Disease, Universitas Airlangga, Surabaya 60115, Indonesia.

Although millions of people have been infected by (), only a small proportion of infected individuals will develop adverse outcomes, ranging from chronic gastritis to gastric cancer. Advanced development of the disease has been well-linked with chronic inflammation, which is significantly impacted by the adaptive and humoral immunity response. From the perspective of cellular immunity, this review aims to clarify the intricate axis between IL-17, IL-21, and IL-23 in -related diseases and the pathogenesis of inflammatory gastrointestinal diseases.

MicroRNAs as the Important Regulators of T Helper 17 Cells: A Narrative Review.

Iran J Allergy Asthma Immunol 2020 Dec 19;19(6):589-601. Epub 2020 Dec 19.

Immunology Research Center, Mashhad University of Medical Sciences, Mashhad, Iran.

T helper (Th)-17 cells are a distinct and important subset of Th cells and their functions are due to the ability of production and secretion of key cytokines in the immune system such as interleukin (IL)-17, IL-22, IL-21, and tumor necrosis factor-α (TNF-α). According to these cytokines, these cells have vital roles in the pathogenesis of the disease such as rheumatoid arthritis (RA) and osteoarthritis (OA). Nowadays, microRNAs (miRNAs) are defined as essential regulators of cell function by targeting transcription factors and other elements that act in cells to control gene expression. Read More

The Role of Gamma-Delta T Cells in Diseases of the Central Nervous System.

Front Immunol 2020 23;11:580304. Epub 2020 Oct 23.

Department of Orthopedics, First Affiliated Hospital, Jinan University, Guangzhou, China.

Gamma-delta (γδ) T cells are a subset of T cells that promote the inflammatory responses of lymphoid and myeloid lineages, and are especially vital to the initial inflammatory and immune responses. Given the capability to connect crux inflammations of adaptive and innate immunity, γδ T cells are responsive to multiple molecular cues and can acquire the capacity to induce various cytokines, such as GM-CSF, IL-4, IL-17, IL-21, IL-22, and IFN-γ. Nevertheless, the exact mechanisms responsible for γδ T cell proinflammatory functions remain poorly understood, particularly in the context of the central nervous system (CNS) diseases. Read More

Department of Clinical Immunology Research of Biochemical Sciences Faculty, Universidad Autónoma "Benito Juárez" de Oaxaca, Oaxaca City 68120, Mexico.

Sjogren´s syndrome (SS) is an autoimmune disease whose pathogenesis is characterized by an exacerbated T cell infiltration in exocrine glands, markedly associated to the inflammatory and detrimental features as well as the disease progression. Several helper T cell subsets sequentially converge at different stages of the ailment, becoming involved in specific pathologic roles. Initially, their activated phenotype endows them with high migratory properties and increased pro-inflammatory cytokine secretion in target tissues. Read More

Roles of cytokines and T cells in the pathogenesis of myasthenia gravis.

Clin Exp Immunol 2021 Mar 3;203(3):366-374. Epub 2020 Dec 3.

Department of Neurology, Hanamaki General Hospital, Hanamaki, Japan.

Myasthenia gravis (MG) is characterized by muscle weakness and fatigue caused by the presence of autoantibodies against the acetylcholine receptor (AChR) or the muscle-specific tyrosine kinase (MuSK). Activated T, B and plasma cells, as well as cytokines, play important roles in the production of pathogenic autoantibodies and the induction of inflammation at the neuromuscular junction in MG.

The inflammation in cutaneous lichen planus is dominated by IFN-ϒ and IL-21-A basis for therapeutic JAK1 inhibition.

Exp Dermatol 2021 Feb 12;30(2):262-270. Epub 2020 Nov 12.

Department of Dermatology, Venereology and Allergology, Charité - Universitätsmedizin Berlin, corporate member of Freie Universität Berlin, Humboldt-Universität zu Berlin, and Berlin Institute of Health, Berlin, Germany.

Cutaneous lichen planus (CLP) and psoriasis (PSO) are both common chronic inflammatory skin diseases for which development of new treatments requires the identification of key targets. While PSO is a typical Th17/IL-17-disorder, there is some evidence that Th1/IFN-ɣ dominate the inflammatory process in CLP. Nonetheless, the immunopathogenesis of CLP is not fully explained and key immunological factors still have to be recognized. Read More
