Background Some studies have revealed enzymatic and non-enzymatic roles of adenosine deaminase (ADA) in male reproductive system such as regulating adenylate cyclase activity by decreasing adenosine concentration, helping to interaction between prostasomes and spermatozoa. MaterialsAndMethods frequency distribution of ADA1 G22A alleles and genotypes in 200 fertile and 200 infertile men. The pol...

Although the pathogenesis of ankylosing spondylitis (AS), which is a systemic disease characterized by inflammation, largely unknown, pro-inflammatory mediators, oxidative stress, and immunity are thought to be involved in development prognosis disease. It was aimed this study reveal activities adenosine deaminase (ADA), cornerstone enzyme different pathways. Twenty nine AS patients 16 healthy ...

The diagnosis of organ disease is aided by measurement of number of nonfunctional plasma enzymes characteristic of that organ/tissue. The amount of enzymes released depends on the degree of cellular damage, the intra-cellular concentration of enzymes, and the mass of the effected tissue. The concentration of enzyme released reflects the severity of damage. Once the presence of hepatic dysfuncti...

Astrocytes are acutely sensitive to 1,3-dinitrobenzene (1,3-DNB) while adjacent neurons are relatively unaffected, consistent with other chemically-induced energy deprivation syndromes. Previous studies have investigated the role of astrocytes in protecting neurons from hypoxia and chemical injury via adenosine release. Adenosine is considered neuroprotective, but it is rapidly removed by extra...

AIM Objective of the study was to evaluate the state of the main indicators of antioxidant status and enzymes of purine metabolism in the germ cells of men living in the zone of ecological catastrophe Aral Sea region. METHODS The criterion for inclusion is the stay of an adult in the Aral Sea area is not less than 5 years, employment in occupations with no more than 2 hazard class. Determinat...

Chronic obstructive pulmonary disease (COPD) has been defined by the Global Initiative for Chronic Obstructive Lung Disease (GOLD), as a disease state characterized by airflow limitation which is not fully reversible. COPD consists of emphysema which is the destruction and inflammation of the lung alveoli. Adenosine deaminase (ADA, E.C.3.5.4.4) converts adenosine to inosine. There are two isoen...

Adenosine is readily available to the glandular epithelium of the stomach. Formed continuously in intracellular and extracellular locations, it is notably produced from ATP released in enteric cotransmission. Adenosine analogs modulate chloride secretion in gastric glands and activate acid secretion in isolated parietal cells through A2B adenosine receptor (A2BR) binding. A functional link betw...

Mutations in the adenosine deaminase (ADA) gene are responsible for a form of severe combined immunodeficiency (SCID) caused by the lymphotoxic accumulation of ADA substrates, adenosine and 2'-deoxy-adenosine. The molecular mechanisms underlying T-cell dysfunction in humans remain to be elucidated. Here, we show that CD4(+) T cells from ADA-SCID patients have severely compromised TCR/CD28-drive...
