background: glaucoma is one of the most common causes of blindness and is usually associated with elevated intraocular pressure. in patients with primary open angle glau-coma the number of trabecular meshwork cells is decreased. death of the trabecular meshwork cells may be a result of apoptosis. objective: to investigate the aqueous humor levels of soluble fas (sfas) and fas-ligand (sfasl) in ...

background the fas receptor/ligand system including soluble forms is the most important apoptotic initiator in the liver. dysregulation of this pathway may contribute to abnormal cell proliferation and cell death and is regarded as one of the mechanisms preventing the immune system from rejecting the tumor cells. objectives to analyze the role of fas system fas/ fas ligand (fas/ fasl) in the mu...

The aim of the study was to evaluate the concentrations of a soluble form of APO-1/Fas antigen (sFas, CD95) and a soluble Ligand for APO-1/Fas antigen (sCD95L, sFasL) in supernatants from CaSki and HeLa cell line cultures after the incubation with All-trans-retinoic acid. HPV-16 and HPV18 - positive cell lines were cultivated with All-trans-retinoic acid in concentrations of 1 x 10(-6) M/L and ...

Background: Soluble FasL (sFasL) generating from Membrane-bound (mFasL) cleaved by matrix metalloproteinases (MMPs). sFasL inhibits the apoptotic and inflammatory activity of mFasL because competes with binds to Fas. To evaluate serum soluble Fas ligand level in patients chronic myeloid leukemia.
 Materials Method: Serum levels were measured ELISA method after venous blood was collected 56...

The aim of the present study was to investigate the expression of Fas in periarticular tenocytes of patients with osteoarthritis (OA) and to study their susceptibility to Fas ligand-mediated apoptosis. Tendon samples were obtained from the quadriceps femoris muscle of patients with knee OA and used for histological evaluation, for immunohistochemical detection of Fas, and to establish tenocyte ...
