Neopterin as an Activity Index in Pulmonary Tuberculosis

Serum neopterin as an objective marker of psoriatic disease activity.

Neopterin is a non-specific marker of the activation of cell-mediated immunity. Several studies have demonstrated the crucial role of CD4+ T cells in the pathogenesis of psoriasis. We have measured serum and urine neopterin levels and urine neopterin/creatinine ratios by radioimmunoassay in 24 patients with plaque-type psoriasis before and after a course of topical treatment with triamcinolone ...

Serum interleukin-2 and neopterin levels as useful markers for treatment of active pulmonary tuberculosis.

Macrophages and T cells are responsible for the main immune response to tuberculosis by secreting many cytokines and other substances. The aim of this study was to determine the effects of multidrug treatment on serum levels of interleukin-2 (IL-2), secreted by activated T cells, and of neopterin, secreted by macrophages and monocytes, in patients with pulmonary tuberculosis. The study included...

A STUDY OF MYCOBACTERIUM TUBERCULOSIS DRUG RESISTANCE IN PULMONARY TUBERCULOSIS

Tuberculosis remains a major public health problem in both developing and developed countries. Drug-resistant tuberculosis is an increasing health problem and serious challenge to tuberculosis (TB) control programs. Information about the susceptibility pattern of Mycobacterium tuberculosis isolates against anti-tuberculosis drugs is an important aspect to TB control. The objectives of the s...

Neopterin acts as an endogenous cognitive enhancer

Neopterin is found at increased levels in biological fluids from individuals with inflammatory disorders. The biological role of this pteridine remains undefined; however, due to its capacity to increase hemeoxygenase-1 content, it has been proposed as a protective agent during cellular stress. Therefore, we investigated the effects of neopterin on motor, emotional and memory functions. To addr...
