  • Publication number: 20160067271
    Abstract: The invention includes methods of treating, preventing, or limiting obesity or weight gain, or reducing or suppressing appetite, by the administration of A2A adenosine receptor pathway agonists. The A2AR pathway agonists may be administered in conjunction with a therapeutic agent having a side effect of weight gain, in order to prevent or limit that weight gain. In some instances, the A2AR pathway agonist is administered as a sleeping pill, and in other instances the A2AR pathway agonist is administered in a non-drowsy formulation.

  • Patent number: 8883500
    Abstract: In the past, adoptive immunotherapy often failed because the transferred immune cells were inactive in vivo. This disclosure provides a method of producing immune cells that are highly active in vivo. The immune cells may be expanded in vitro in the presence of an adenosine receptor agonist or an antisense nucleic acid that downregulates expression of an adenosine receptor, for example. The immune cells may be tumor-infiltrating lymphocytes (TIL), cytotoxic T lymphocytes (CTL), natural killer (NK) cells, or lymphokine-activated killer (LAK) cells, for example. The methods described herein may be used to treat a number of diseases including cancer, infectious diseases, and immunodeficiencies.
