Abstract

Lyme borreliosis is a chronic infectious disease caused by Borrelia burgdorferi spirochete. The excess and inadequate inflammatory response and even autoimmunity is considered to participate in its pathogenesis. Apoptosis (programmed cell death) of activated lymphocytes contributes to regulation of immunological response and terminating the inflammation. To evaluate concentrations of soluble factors participating in regulation of apoptosis in the supernatants of the peripheral blood mononuclear cells (PBMC) of patients with chronic Lyme borreliosis. The study group consisted of 10 patients with chronic Lyme arthritis and the control group of 5 persons in whom Lyme borreliosis was excluded. In the supernatant of PBMC culture incubated with Borrelia burgdorferi antigens concentrations of potentially anti-apoptotic factors: soluble receptor for tumor necrosis factor alpha (sTNF-RI), soluble Fas (sFas) and soluble Fas ligand (sFasL), as well as the concentration of transforming growth factor beta (TGF-beta), cytokine synthesized in the final stage of apoptosis, were measured by ELISA. Concentrations of sTNF-RI, sFas and sFasL, but also TGF-beta tended to be increased in the study group in comparison with nonstimulated PBMC and the ...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Autoimmune Diseases

Autoimmune diseases occur as a result of an attack by the immune system on the body’s own tissues resulting in damage and dysfunction. There are different types of autoimmune diseases, in which there is a complex and unknown interaction between genetics and the environment. Discover the latest research on autoimmune diseases here.
