Gender differences in multiple sclerosis: cytokines and vitamin D

Area of Science:

• Neurology
• Immunology
• Endocrinology

Background:

• Multiple sclerosis (MS) exhibits a growing disparity in the female:male ratio, particularly in relapse-onset forms.
• This trend suggests a significant role for gender in MS pathogenesis, mirroring patterns observed in other autoimmune diseases.

Purpose of the Study:

• To review and highlight the key gender differences observed in multiple sclerosis (MS).
• To emphasize the influence of cytokines and vitamin D on these gender-specific aspects of MS.

Main Methods:

• Literature review focusing on studies investigating gender differences in MS.
• Analysis of research on the role of immune system components, specifically cytokines.
• Examination of the impact of hormonal factors and vitamin D levels on MS in different genders.

Main Results:

• The female predominance in MS is disproportionately increasing.
• Cytokines, key immune system mediators, are implicated in MS gender disparities.
• Hormonal fluctuations and vitamin D levels, influenced by seasonal changes, modulate immune responses relevant to MS.

Conclusions:

• Gender significantly impacts multiple sclerosis (MS) presentation and potentially progression.
• Immune system modulation via cytokines, hormones, and vitamin D are critical factors in understanding MS gender differences.
