The definition of immune Thrombocytopenia (ITP) as a peripheral blood platelet count less than 100 × 10⁹/L instead of the historical criteria of 150 × 10⁹/L renders subjects with platelets between 100 and 150 × 10⁹/L without a diagnosis. Here, we demonstrated that these subjects have enhanced levels of proinflammatory cytokines linked to Th1 and Th17 cell response, and are more frequently carri...

Background: Although many experimental studies provide convincing evidence that type II immunity is protective against helminths, recent data in mice demonstrate that Th1 is also impor-tant in some cestodes like Hymenolepis nana. Objective: To identify the role of Th1 and Th2 lymphocytes in immunity against H. nana, the levels of IL-12, IFNγ, IL-5, and IL-13 were de-termined in serum of humans ...

The story of cytokines goes back to last century when interferon was discovered first time. Cytokines are pleiotropic proteins or small glycoproteins with a molecular weight less than 30 kDa (˂200 amino acids) Cytokines are produced by a number of cell types, such as leukocytes which regulate immunity, inflammation and hematopoiesis [1]. About 200 cytokines are recognized to date. They have a h...

Evidence is accumulating that Th1 cells play an important role in the development of multiple sclerosis (MS) and experimental allergic encephalomyelitis (EAE), whereas Th2 cells contribute to recovery from disease. A major determinant in the development of Th1 and Th2 cells is the type of antigen-presenting cell (APC) involved and its functional characteristics, e.g., the production of interleu...

We investigated the rotavirus-specific lymphocyte responses induced by intranasal immunization of adult BALB/c mice with rotavirus 2/6 virus-like particles (2/6-VLPs) of the bovine RF strain, by assessing the profile of cytokines produced after in vitro restimulation and serum and fecal antibody responses. The cytokines produced by splenic cells were first evaluated. Intranasal immunization wit...

Pemphigus vulgaris (PV) is a chronic autoimmune blistering disease of the skin, in whichloss of adhesion between keratinocytes is caused by autoantibodies. It has been hypothesizedthat cytokines play an essential role in the pathogenesis of PV. This study aimed to investigatethe other immunopathological aspects of PV by determining the serum levels of cytokines inPV patients to find another tre...

OBJECTIVE To assess whether DC from RA produce altered cytokine levels and whether this is regulated by triggering of Fc gamma receptors (FcgammaR). METHODS The production of proinflammatory (TNFalpha, IL1, IL6), Th1 (IL12, IFNgamma), and Th2 (IL10) cytokine profiles of immature DC (iDC) from patients with RA and healthy subjects upon triggering of FcgammaR dependent and independent pathways ...

BACKGROUND Neuro-Sweet disease (NSD) has recently been identified as Sweet disease with central nervous system (CNS) involvement characterized by multisystem neutrophilic infiltration. However, the pathogenesis of this disease remains unknown. Neutrophil and other inflammatory cell activities are influenced by many cytokines and chemokines, but to date, no studies have examined the levels of th...
