Neutrophil degranulation: therapeutic targets in [NTP]O mediated neutrophil degranulation

Medical Hypotheses
S Kannan

Abstract

Extracellular nucleotide-induced stimulation and activation of peripheral blood neutrophil and subsequent degranulation plays a critical role in immediate type hypersensitivity reaction and other inflammatory diseases. The extracellular nucleotides stimulate a P2Y receptor(s) on human PMN with the pharmacological profile similar to that of the P2Y2 receptor. Based on a recent proposal on the molecular mechanism of [NTP]O-induced neutrophil degranulation, a scheme identifying the therapeutic targets, is suggested with potential avenues for attenuating PMN degranulation.

Atopic Dermatitis

Atopic dermatitis is a chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus.

Allergy and Asthma

Allergy and asthma are inflammatory disorders that are triggered by the activation of an allergen-specific regulatory t cell. These t cells become activated when allergens are recognized by allergen-presenting cells. Here is the latest research on allergy and asthma.
