Human immune system: Exploring diversity across individuals and populations

Area of Science:

• Immunology
• Genetics
• Environmental Health

Background:

• The immune response is a complex system of cellular and molecular components with specialized functions.
• Immune responses are adaptable, influenced by genetic diversity (ethnic/racial variations) and environmental factors (geography, socioeconomic status).
• Genetic and environmental factors influence disease incidence, susceptibility, autoimmune disorders, and cancer risks.

Purpose of the Study:

• To systematically review and organize findings on immune diversity.
• To highlight the need for understanding immune indices across races and populations.
• To emphasize the potential for targeted interventions to address health disparities and advance translational research.

Main Methods:

• Systematic review of existing literature.
• Analysis of genetic and environmental influences on immune responses.
• Organization of findings to identify gaps in knowledge.

Main Results:

• Genetic diversity significantly impacts disease susceptibility and risks across populations.
• Environmental factors modulate immune system responses, affecting susceptibility to infections and autoimmune disorders.
• A gap exists in understanding race-specific immune indices and population-based immune reference ranges.

Conclusions:

• Deeper understanding of immune diversity is essential for personalized diagnostics and therapeutics.
• Targeted interventions based on genetic and environmental factors can address health disparities.
• This approach promises advancements in identifying specific immunological conditions and tailoring treatments.
