Serum thymic hormone activity in genetically-obese mice
The British Journal of Nutrition
|January 1, 1981
Summary
Obesity in mice is linked to higher serum thymic hormone levels and an increased number of antibody-forming cells. These findings suggest obesity may impact immune cell populations and function.
Area of Science:
- Immunology
- Endocrinology
- Obesity Research
Background:
- Obesity is a complex metabolic condition with potential implications for immune system function.
- The thymus gland produces hormones crucial for T-cell development and immune regulation.
Purpose of the Study:
- To investigate the relationship between genetic obesity and serum thymic hormone levels.
- To assess the impact of obesity on immune cell populations, specifically antibody-forming cells.
Main Methods:
- Assay of serum thymic hormone in genetically obese (C57B1/6J ob/ob) mice and lean controls.
- Quantification of antibody-forming cells in the spleen as a proportion of total mononuclear cells.
Main Results:
- Serum thymic hormone activity was significantly higher in obese mice compared to lean controls.
- Obese mice exhibited an increased proportion of antibody-forming cells in their spleen.
Conclusions:
- Obesity is associated with altered thymic hormone levels.
- Changes in thymic hormone may influence lymphocyte subset proportions and cell-mediated immunity in obese individuals.
