Abstract: Provided are exosomes sourced from a granulocyte myeloid-derived suppressor cell and an application thereof. The exosomes are named as G-MDSC exo. Also provided is a use of the exosomes in preparing a drug used for suppressing autoimmune diseases. The G-MDSC exo can effectively suppress proliferation of CD4+T cells in vitro, promote induced proliferation of T regulatory (Treg) cells, alleviate foot swelling of model mice having delayed-type hypersensitivity, and suppress attacks of inflammatory bowel disease (IBD) and collagen-induced arthritis (CIA) of the mice.

Abstract: The present invention provides methods and compositions for modulating levels of amyloid-? peptide (A?) exhibited by cells or tissues. The invention also provides pharmaceutical compositions and methods of screening for compounds that modulate A? levels. The invention also provides modulation of A? levels via selective modulation (e.g., inhibition) of ATP-dependent ?-secretase activity. The invention also provides methods of preventing, treating or ameliorating the symptoms of a disorder, including but not limited to an A?-related disorder, by administering a modulator of ?-secretase, including, but not limited to, a selective inhibitor of ATP-dependent ?-secretase activity or an agent that decreases the formation of active (or optimally active) ?-secretase. The invention also provides the use of inhibitors of ATP-dependent ?-secretase activity to prevent, treat or ameliorate the symptoms of Alzheimer's disease.

Abstract: Disclosed herein are compositions and methods relating to the modulation of Appoptosin levels or activity in the treatment of Neurodegenerative disorders or cancer.

Abstract: The present invention provides methods and compositions for modulating levels of amyloid-&bgr; peptide (A&bgr;) exhibited by cells or tissues. The invention also provides pharmaceutical compositions and methods of screening for compounds that modulate A&bgr; levels. The invention also provides modulation of A&bgr; levels via selective modulation (e.g., inhibition) of ATP-dependent &ggr;-secretase activity. The invention also provides methods of preventing, treating or ameliorating the symptoms of a disorder, including but not limited to an A&bgr;-related disorder, by administering a modulator of &ggr;-secretase, including, but not limited to, a selective inhibitor of ATP-dependent &ggr;-secretase activity or an agent that decreases the formation of active (or optimally active) &ggr;-secretase. The invention also provides the use of inhibitors of ATP-dependent &ggr;-secretase activity to prevent, treat or ameliorate the symptoms of Alzheimer's disease.
