Chondrocyte tumor necrosis factor receptors and focal loss of cartilage in osteoarthritis

Evaluation of Tumor Necrosis Factor Alpha Polymorphism Frequencies in Endometriosis

Background The pro-inflammatory cytokine, tumor necrosis factor-alpha (TNF-α), is a pathogenic element for a number of disorders. Previous studies have reported that the -1031 T/C and -238 G/A polymorphisms in the promoter region of the TNF-α gene are important factors in reproductive-related disorders. One of the most common gynecological diseases of women during the reproductive years is endo...

CIRCULATING SOLUBLE TUMOR NECROSIS FACTOR RECEPTORS, INTERLEUKIN-2 RECEPTORS, TUMOR NECROSIS FACTOR a, AND INTERLEUKIN-6 LEVELS IN RHEUMATOID ARTHRITIS

Tumor necrosis factor: receptors on hematopoietic cells.

Tumor necrosis factor (TNF) is a monokine that is cytotoxic/cytostatic for a variety of tumor cells and has multiple effects on normal cells. We demonstrate that normal and malignant human myeloid cells express a single class of high-affinity receptors (400 to 1,900 per cell, KD 20 to 90 pmol/L) for TNF. Mitogen-stimulated lymphocytes have a similar number of TNF receptors, whereas resting lymp...

Chondrocyte-mediated collagenolysis correlates with cartilage destruction grades in osteoarthritis.

OBJECTIVE Osteoarthritis (OA) is associated with destruction of type II collagen-rich hyaline articular cartilage. We hypothesized that classical interstitial collagenases cleave collagen type II, leading to the increased expression of the 3/4 native type II collagen fragment (COL2-3/4C) and the corresponding denatured type II collagen fragment (COL2-3/4M), which could correlate with different ...
