IL-4 fails to regulate in vitro beryllium-induced cytokines in berylliosis

IL-4 fails to regulate in vitro beryllium-induced cytokines in berylliosis.

Bronchoalveolar lavage (BAL) cells from patients with chronic beryllium disease (CBD) have been used to evaluate the beryllium-specific immune response and potential immunotherapeutics. Beryllium induces interferon-gamma (IFN-gamma), interleukin-2 (IL-2), tumour necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6) and interleukin-10 (IL-10) from BAL cells. An antibody to IL-2 and recombinant...

Interacting cytokines regulate in vitro human megakaryocytopoiesis.

The effects of hematopoietic growth factors on in vitro human megakaryocytopoiesis were studied using a serum-depleted culture system. Both recombinant interleukin-3 (r-IL-3) and recombinant granulocyte-macrophage colony-stimulating factor (rGM-CSF) increased megakaryocyte (MK) colony formation (P less than .01) above that observed in baseline cultures. Recombinant interleukin-4 (rIL-4) and int...

Cytokines (IL-17, IL-23, and IL-33) in Systemic lupus erythematosus in Trinidad and Tobago.

Systemic lupus erythematosus (SLE) is the most common autoimmune disease. It is characterized by the presence of hundreds of autoantibodies against many organs and tissues, including the presence of a large number of autoantibodies, which are specific to self-antigens mainly of nuclear origin such as Smith antigen, double-stranded DNA (dsDNA), anti-Sjögren’s syndrome-related antigen A and B (SS...

IL-4 Can Inhibit IL-17 Production in Collagen Induced Arthritis

Background: IL-4 is a cytokine that induces differentiation of naive helper T cells into Th2 cells. Once activated by IL-4, Th2 cells subsequently produce additional IL-4. Objective: To examine the effect of IL-4 on IL-17 production and its effect in Collagen- Induced Arthritis (CIA) mice. Method: In this study, a chicken collagen-II-induced experimental arthritis (CIA) model was used in DBA/1 ...
