Matrix metalloproteinases (MMPs) catalyze extracellular matrix degradation. Control of their activity is a promising target for therapy of diseases characterized by abnormal connective tissue turnover. MMPs are expressed as latent proenzymes that are activated by proteolytic cleavage that triggers a conformational change in the propeptide (cysteine switch).(More)
The three-dimensional structure of human tissue inhibitor of metalloproteinases-2 (TIMP-2) was determined by X-ray crystallography to 2.1 A resolution. The structure of the inhibitor consists of two domains. The N-terminal domain (residues 1-110) is folded into a beta-barrel, similar to the oligonucleotide/oligosaccharide binding fold otherwise found in(More)
Extragenital chlamydial complications may be associated with systemic spread of infection, but haematogenous route for C. trachomatis dissemination has not been clearly demonstrated. Here we report that serum specimens obtained from patients with chlamydiosis contain elementary bodies of C. trachomatis shown by culture and immunogold electron microscopy. We(More)
Chlamydia and antibodies to them were detected by serological, molecular biological, and culture methods in the sera and cerebrospinal fluid of patients with multiple sclerosis and in the reference groups of subjects without neurological diseases. Correlations between the agent presence in the biological fluids of patients and clinical characteristics of(More)
