Abstract: Combination therapies of substituted quinolines and substituted diphenyl sulfones are disclosed. More specifically, compositions containing substituted quinolines and substituted diphenyl sulfones are disclosed. In addition, methods of using the compositions in the treatment of neurodegenerative disorders, including, inter alia, Alzheimer's dementia, HIV-1 associated dementia, and Creutzfeld-Jakob disease are also disclosed.

Abstract: Encephalotoxin produced by activated mononuclear phagocytes is present in individuals having neurological disease including neurodegenerative and neuro-inflammatory diseases, such as Azlheimer's disease (AD), HIV-1-associated dementia (HAD), Creutzfeld-Jakob disease, Mild Cognitive Impairment, prion disease, mild congnitive/motor dysfunction, acute stroke, acute trauma, or neuro-AIDS. Biochemical detection of encephalotoxin according to the methods of the invention will allow diagnosis of neurological disease in early, presymptomatic stages, thereby allowing early intervention in disease progression as well as identification of subjects or populations at risk for developing neurodegenerative disease. The methods of the invention also provide a mechanism for monitoring progression and treatment of neurological disease.

Abstract: The present invention is directed to screening for an agent that inhibits the effect of a neurotoxin from a plaque component activated mononuclear phagocyte on a neuron. In addition, the present invention is directed to methods of screening for agents that inhibit mononuclear phagocyte-plaque component complex formation, plaque component activation of a mononuclear phagocyte, plaque component induced neurotoxicity of a mononuclear phagocyte. An agent obtained by the method of screening for an agent that inhibits mononuclear phagocyte-plaque component complex formation and a pharmaceutical composition comprising the agent are embodied by the present invention.

Abstract: The present invention is directed to screening for an agent that inhibits mononuclear phagocyte-plaque component complex formation (hereinafter "complex formation"). The methods include the steps of contacting a mononuclear phagocyte with a plaque component to stimulate complex formation and adding an agent suspected of inhibiting complex formation, measuring complex formation, and comparing complex formation to a measured control, wherein the reduction of complex formation compared to the control results in detection of an agent that inhibits complex formation. The mononuclear phagocytes may be from mammalian brain. The plaque component may be coupled to a solid support.
