Gender differences in autoimmunity associated with exposure to environmental factors

Area of Science:

• Immunology
• Environmental Health
• Genetics

Background:

• Autoimmunity arises from genetic, environmental, and stochastic factors, with gender being a key risk factor, often showing a female bias.
• While environmental triggers like medications are known to induce autoimmunity, the interaction between gender, environment, and autoimmunity is less understood.

Purpose of the Study:

• To review the contribution of gender to autoimmunity induced by chemical, physical, and biological agents in humans and animal models.
• To explore the complex interplay between gender, environmental exposures, and the development of autoimmune diseases.

Main Methods:

• Review of epidemiological studies on human autoimmunity.
• Analysis of animal model studies investigating gender-specific autoimmune responses.
• Examination of environmental factors contributing to gender-biased autoimmunity.

Main Results:

• Environmental factors are associated with gender bias in human autoimmunity, often linked to occupational or gender-biased activities.
• Animal studies indicate that gender bias in autoimmunity can be strain-specific, suggesting gene-environment interactions.
• The influence of sex chromosome complement and background genes on immune responses in the context of environmental exposures is highlighted.

Conclusions:

• Gender plays a significant role in environmentally-induced autoimmunity, but its contribution can vary.
• Environmental factors add complexity to the relationship between sex chromosome complement and immune responses in autoimmunity.
• Further research is essential to elucidate how environmental exposures modulate immune responses and influence gender's role in autoimmunity.
