GM1-like peptides and uses thereof
Compositions and methods relating to interfering with the interaction of gangliosides, such as GM1, with their ligands are provided. For example, methods are provided for treating infections by blocking the infectious agent from binding with GM1 using GM1-like peptides. Also provided are methods of inhibiting ligands from binding to GM1 on the surface of cells and for neutralizing anti-GM1 antibodies in neurological diseases.

2. A peptide consisting of SEQ ID NO:3.
3. A composition comprising a peptide of claim 1 .
4. The composition of claim 3 , further comprising a therapeutic agent.
5. The composition of claim 3 , further comprising a detectable agent.
6. The composition of claim 1 , wherein the peptide is 50 amino acids or less.
