Histamine, Neuroinflammation and Neurodevelopment: A Review

Area of Science:

• Neuroscience
• Developmental Biology
• Immunology

Background:

• Histamine, a biogenic amine, modulates brain inflammation and neuronal function.
• Reduced histamine synthesis is linked to Tourette's syndrome and obsessive-compulsive disorder.
• Neuroinflammation impacts brain development, and histamine deficiency may increase vulnerability.

Purpose of the Study:

• To review the impact of non-neuronal histamine sources on neuroinflammation and brain development.
• To examine histamine's role in neural circuits underlying neurodevelopmental disorders.
• To discuss the efficacy of histamine receptor modulators in treating these disorders.

Main Methods:

• Literature review of studies on non-neuronal histamine sources.
• Analysis of in vitro and in vivo research on histamine's effects.
• Synthesis of findings on histamine receptor modulators in preclinical and clinical studies.

Main Results:

• Non-neuronal histamine influences microglial-mediated neuroinflammation.
• This inflammation can affect synaptic plasticity and synaptogenesis during development.
• Evidence suggests histamine deficiency impacts brain development and vulnerability to inflammation.

Conclusions:

• Non-neuronal histamine sources significantly impact brain development and neuroinflammation.
• Histamine modulation presents potential therapeutic avenues for neurodevelopmental disorders.
• Targeting both neuronal and non-neuronal histamine sources may offer novel treatment strategies.
