Methods of treatment and prevention of diet-induced obesity and sequelae thereof

Disclosed are methods of treating or preventing diet-induced obesity and/or one or more sequelae thereof in a subject. These methods comprise administering to a subject in need of treatment or at risk for developing diet-induced obesity and/or one or more sequelae thereof, a therapeutically effective amount of a pharmaceutical composition comprising at least one inhibitor of RP 105 and/or MD-I activity. Also disclosed are methods of identifying compounds that inhibit development of diet-induced obesity and/or one or more sequelae thereof. In some aspects, these methods comprise: providing at least one first cell comprising TLR4, MD-2. RP105. MD-K and a TLR4-responsive promoter operably linked to a nucleic acid sequence encoding a reporter, contacting the at least one first cell with lipopolysaccharide and with a candidate compound; and determining a level of expression of the reporter in the presence of the LPS and the candidate compound, in some aspects, these methods comprise: providing at least one first cell comprising TLR2, TLR1, TLR6, MD-2, RP H/S, MD-K and a TLR2-responsive promoter operably linked to a nucleic acid sequence encoding a reporter, contacting the at least one first cell with a lipopepude ligand of TLR2 and with a candidate compound, and determining a level of expression of the reporter in the presence of the lipopeptide ligand of TLR2 and the candidate compound.
