Summary

  1. 1.

    Chronic ingestion of caffeine by male NIH strain mice alters the density of a variety of central receptors.

     
  2. 2.

    The density of cortical A1 adenosine receptors is increased by 20%, while the density of striatal A2A adenosine receptors is unaltered.

     
  3. 3.

    The densities of corticalβ1 and cerebellarβ2 adrenergic receptors are reduced byca. 25%, while the densities of corticalα1 andα2 adrenergic receptors are not significantly altered. Densities of striatal D1 and D2 dopaminergic receptors are unaltered. The densities of cortical 5 HT1 and 5 HT2 serotonergic receptors are increased by 26–30%. Densities of cortical muscarinic and nicotinic receptors are increased by 40–50%. The density of cortical benzodiazepine-binding sites associated with GABAA receptors is increased by 65%, and the affinity appears slightly decreased. The density of cortical MK-801 sites associated with NMDA-glutaminergic receptors appear unaltered.

     
  4. 4.

    The density of cortical nitrendipine-binding sites associated with calcium channels is increased by 18%.

     
  5. 5.

    The results indicate that chronic ingestion of caffeine equivalent to about 100 mg/kg/day in mice causes a wide range of biochemical alterations in the central nervous system.
