Role of nitric oxide in parasitic infections

Role of nitric oxide in parasitic infections.

Nitric oxide is produced by a number of different cell types in response to cytokine stimulation and thus has been found to play a role in immunologically mediated protection against a growing list of protozoan and helminth parasites in vitro and in animal models. The biochemical basis of its effects on the parasite targets appears to involve primarily inactivation of enzymes crucial to energy ...

The Role of Nitric Oxide in Mycobacterial Infections

Although tuberculosis poses a significant health threat to the global population, it is a challenge to develop new and effective therapeutic strategies. Nitric oxide (NO) and inducible NO synthase (iNOS) are important in innate immune responses to various intracellular bacterial infections, including mycobacterial infections. It is generally recognized that reactive nitrogen intermediates play ...

The role of hippocampal nitric oxide in passive avoidance learning

Abstract: Introduction: Nitric oxide (NO) is a retrograde messenger in hippocampal synaptic plasticity which involves in learning and memory processes. Previous studies revealed that hippocampal pyramidal cells contain NO synthase (NOS) enzyme which produce NO and could be a promising target to evaluate the role of NO in brain cognitive functions. So in this study, using NOS inhibitor (L-NAME)...

Does nitric oxide play a critical role in viral infections?

Involvement of nitric oxide and its up/down stream molecules in the immunity against parasitic infections.

Nitric oxide (NO) is a potent mediator with diverse roles in regulating cellular functions and signaling pathways. The NO synthase (NOS) enzyme family consists of three major isoforms, which convey variety of messages between cells, including signals for vasorelaxation, neurotransmission and cytotoxicity. This family of enzymes are generally classified as neuronal NOS (nNOS), endothelial NOS (e...
