Study Notes

Self and Non-Self Recognition

The immune system distinguishes between "self" cells (belonging to the body) and "non-self" cells (foreign invaders).
Major Histocompatibility Complex 1 (MHC1) acts as a self-tag on cells, preventing immune attacks from phagocytes and other immune cells.
Clonal Deletion eliminates B cells during maturation in the bone marrow if they possess receptors recognizing self-tissue, preventing autoimmunity.
Positive and Negative Selection processes in the thymus ensure T cells differentiate between self and non-self tissues, preventing potential autoimmune attacks.

Factors Contributing to Autoimmunity

Genetics: A genetic predisposition may increase the likelihood of developing autoimmune conditions.
Infection: Certain infections, like Epstein-Barr Virus (EBV), might contribute to the development of autoimmune diseases.
Gender: Women, particularly those between 15-50, are at a higher risk for autoimmunity compared to men. This may be linked to the "extra X" chromosome, which can offer immune protection but potentially also contribute to an overactive immune state.
Environmental Factors: Environmental factors like UV light exposure, certain medications, and smoking can influence the risk of developing autoimmunity.

Autoimmune Diseases

There are currently over 100 identified autoimmune diseases, including Type 1 Diabetes, Lupus, Multiple Sclerosis, Rheumatoid Arthritis, and Celiac Disease.
Significant disparities in medical research have historically focused on white men, leading to underrepresentation of women and ethnic and racial minorities in studies.

Immune System Recognizing Self vs. Non-Self

Immune cells differentiate between "self" cells, belonging to the body, and foreign cells, which should be destroyed.
MHC1 acts as a "self" tag on cells, preventing immune attacks from phagocytes and other immune cells.
Clonal Deletion eliminates B cells with receptors recognizing self-tissue during maturation in the bone marrow, preventing autoimmune reactions.
Positive and Negative Selection in the thymus ensures T cells can recognize foreign antigens but not attack self-tissues.

Factors Contributing to Autoimmunity

Genetics: While not a direct cause, genetic predisposition can increase the likelihood of developing autoimmune conditions.
Infection: Certain infections, like Epstein Barr Virus (EBV) infection, may increase susceptibility to autoimmunity, but not a direct cause.
Being Female: Women, especially 15-50 years old, have a higher risk of autoimmune conditions potentially linked to the additional X chromosome offering immune protection but potentially contributing to an overactive immune system in some women.
Environmental Factors: UV light exposure, medications, and smoking can affect the risk of developing autoimmunity, but are not the sole cause.

Autoimmune Conditions

Over 100 recognized autoimmune diseases include Type 1 diabetes, lupus, multiple sclerosis, rheumatoid arthritis, and celiac disease.
Important Note: Research has historically focused on white men, excluding women and minorities, leading to a lack of understanding and representation of autoimmune conditions in these groups.

Autoimmune Conditions

The immune system mistakenly attacks the body's own tissues.
Over 80 recognized autoimmune conditions exist, including lupus, rheumatoid arthritis, and multiple sclerosis.
Autoimmune conditions are a leading cause of death and disability, impacting 3% to 10% of the global population.
Autoimmune conditions are significantly more prevalent in women, with 75% of US cases occurring in individuals who identify as female.

The Gender Bias of Autoimmunity

The prevalence disparity between genders is a medical mystery.
Early research focused on sex hormones as a possible cause.
Testosterone suppresses immune function and reduces B cells, which produce antibodies.
Estrogen and other female sex hormones are also implicated.
Scientists are researching the role of sex chromosomes, particularly the X chromosome's abundance of immune-related genes.
The Y chromosome's multicopy genes are another potential factor, but research is still in early stages.

Potential Explanations for the Gender Bias

X-linked genes are potential contributors to autoimmunity, potentially explaining the higher prevalence in individuals with two X chromosomes.
X chromosome inactivation, where one X chromosome is deactivated in females, might contribute to autoimmunity.
Skewed X chromosome inactivation, where one X chromosome is predominantly active, has been associated with autoimmune conditions.
The pregnancy compensation hypothesis suggests that the prevalence in women could be linked to pregnancy rate changes and the associated immune system adaptations.
The immune system during pregnancy adapts to tolerate half-foreign cells, possibly explaining the difference in immune function between people with and without uteruses.

Future Research and Treatment

Ongoing research focuses on the potential role of sex hormones, sex chromosomes, and evolutionary factors in autoimmunity.
Understanding the underlying causes could lead to new treatments and potential cures.
The pregnancy compensation hypothesis could offer avenues for treatment, including mimicking the immune benefits of pregnancy without actual pregnancies.

Autoimmune Conditions

Autoimmune conditions occur when the immune system mistakenly attacks the body's own tissues.
There are over 80 identified autoimmune conditions.
Autoimmune conditions are often chronic and debilitating.
They are a leading cause of death and disability worldwide, affecting an estimated 3-10% of the population.

Gender Bias in Autoimmune Conditions

Women are disproportionately affected by autoimmune conditions, accounting for 75% of US cases.
The scientific reason for this gender bias remains unknown.

Historical Context and Research Barriers

Early research in immunology was influenced by sexist biases that limited understanding of autoimmune conditions.
These biases included understudying conditions primarily affecting women and dismissing women's concerns.
The term "horror autotoxicus" reflected the belief that autoimmune conditions were impossible due to the lack of antibodies against self-tissues.
This belief hampered research into autoimmune conditions for decades.

Discovering Autoimmunity

In 1946, a British immunologist developed a test to detect autoantibodies, advancing research in the field.
The discovery of rheumatoid factor, an autoantibody present in rheumatoid arthritis, provided further evidence.
In 1964, a global immunology conference officially recognized autoimmunity as a valid medical condition.

The Search for the Root Cause

Researchers are investigating various factors that might contribute to the gender bias in autoimmune conditions, including genetic, hormonal, and environmental factors.
The exact cause of autoimmune conditions is still under investigation.

Sex Hormones as a Possible Factor

The role of sex hormones in autoimmune conditions is complex and uncertain.
Some studies suggest that testosterone, present in higher levels in men, may suppress immune function, potentially reducing autoimmune risk.
Other studies propose a role for estrogen, generally higher in women.
Further research is needed to understand the specific role of sex hormones in autoimmunity.

The X Chromosome and Autoimmunity

The X chromosome contains more immune-related genes than any other chromosome.
This has led to hypotheses suggesting that the number of X chromosomes might influence autoimmune susceptibility.
People with Klinefelter's syndrome (XXY), who have an extra X chromosome, show a higher prevalence of autoimmune conditions, supporting the X chromosome hypothesis.

The X chromosome contains genes that could lead to overproduction of certain proteins, potentially triggering autoimmunity.
X chromosome inactivation, the process of silencing one X chromosome in cells with two Xs, may be involved.
Stress can disrupt X chromosome inactivation, leading to the production of proteins that the immune system misidentifies as foreign.
Skewed X chromosome inactivation, where one X is predominantly active in most cells, has been linked to autoimmune conditions.

The Y Chromosome and Autoimmunity

The Y chromosome also carries immune-related genes and has unique features, including repetitive DNA sequences.
The role of the Y chromosome in autoimmune susceptibility is a relatively new area of research.
Further investigation into the Y chromosome's influence could reveal new insights and potential treatment options.

The Pregnancy Compensation Hypothesis

A recent hypothesis suggests that autoimmune conditions are more prevalent due to a decrease in the number of pregnancies per person over time.
Pregnancy involves tolerance towards semi-foreign fetal cells, potentially influencing immune system development and function.
This hypothesis suggests that pregnancy might modulate the immune system and reduce the risk of autoimmune conditions.
More research is needed to explore this hypothesis.

Conclusion

Although significant progress has been made, the factors behind the gender bias in autoimmune conditions remain complex and an active area of research.
Multiple factors might contribute to autoimmune conditions, with different conditions potentially having distinct causes.
Further investigation into genetics, hormones, and environmental factors, including the pregnancy compensation hypothesis, offers promise for understanding and treating autoimmune conditions.
