  • which is a major reason for the regaining of lost weight with dieting as well being the mechanism behind stress induced weight gain (it is not due to increased cortisol).
  • f greater than 10, it demonstrates there is a degree of leptin resistance contributing to an inability to lose weight
  • that it is difficult to lose weight with leptin resistance. High carbohydrate diets and in particular high-fructose corn syrup is shown to significantly increase leptin resistance and is a likely mechanism that high fructose corn syrup is associated with obesity

  • inactive thyroid hormone called thyroxine
  • it is problem inside the cell that the inactive T4 is not converted to T3 but rather to a mirror image of T3 called reverse T3. The reverse T3 has the opposite effect of T3, blocking the effects of T3 and lowering rather than increasing metabolism.
  • Studies are showing that stress and dieting (especially yo-yo dieting) can set this hormone into action as well as chronic illness such as diabetes, chronic fatigue syndrome and fibromyalgia.
  • As soon as the body senses a reduction in calories, the production of reverse T3 is stimulated to lower metabolism
  • With chronic dieting or stress, the body often stays in this "starvation mode" with elevated levels of reverse T3 and decreased levels of T3, which is a major reason for the regaining of lost weight with dieting as well being the mechanism behind stress induced weight gain (it is not due to increased cortisol).
  • which is a major reason for the regaining of lost weight with dieting as well being the mechanism behind stress induced weight gain (it is not due to increased cortisol).
  • which is a major reason for the regaining of lost weight with dieting as well being the mechanism behind stress induced weight gain (it is not due to increased cortisol).

BPA plastics endocrine disruptor immune T reg cells

shared by Nathan Goodyear on 01 Jul 11 - No Cached
  • BPA promotes the development of TH2 cells in adulthood and both TH1 and TH2 cells in prenatal stages by reducing the number of regulatory T cells.
  • Bisphenol A (BPA), an estrogenic endocrine-disrupting chemical (EDC
  • BPA is one of the most widespread EDCs.
  • ...12 more annotations...
  • BPA antagonizes the actions of thyroid hormone
  • Prenatal exposure to BPA has been shown to alter a variety of reproductive endocrine parameters, such as testosterone and luteinizing hormone levels
  • arly onset of sexual maturation of female mice
  • imbalanced T-helper (TH)1/TH2 immune responses have been demonstrated on exposure to BPA
  • indicating that BPA exerted its effects by reducing the number of Treg cells.
  • Exposure to BPA by subcutaneous injection in adulthood significantly promoted antigen-stimulated production of IL-4, IL-10, and IL-13 in TH2-skewed
  • BPA can leak from the placenta and accumulate in the fetus
  • We showed that prenatal exposure to BPA increased the production of a TH1 cytokine, IFN-γ, and a TH2 cytokine, IL-4, after the offspring developed, suggesting that prenatal exposure to BPA can induce persistent immunologic effects lasting into adulthood.
  • These results are consistent with a previous report that fetal exposure to BPA augmented TH1 and TH2 immune responses
  • our results clearly demonstrate that the production of TH2 cytokines is promoted by BPA in adult mice and in offspring during developmental exposure.
  • The decrease of Treg cells would predispose to immune dysfunction in aged individuals, explaining their higher risk of immune-mediated diseases, cancer, and infections.
  • BPA might cause these diseases. Thus, avoiding exposure to or promoting the excretion of BPA and other EDCs would help in preventing diseases and adverse health effects.
