Use of the antimicrobial cathelicidin peptide II-37, N-terminal fragments of LL-37 or extended sequences of LL-37 having 1-3 amino acids in the C-terminal end, for stimulating proliferation of epithelial and stromal cells and thereby healing of wounds, such as chronic ulcers. The cytotoxic effect of LL-37 may be reduced by including a bilayer-forming polar lipid, especially a digalactosyldiacylglycerol, in pharmaceutical compositions and growth media comprising LL-37.

Use of the cathelicidin LL-37 and derivatives thereof for wound healing

Use of the cathelicidin LL-37 and derivatives therof for wound healing

The present invention provides agents for inhibiting the proliferation of cancer cells, wherein the agent inhibits the biological activity of hCAP18/LL-37. In a preferred embodiment, the agent alters the transcription, translation and/or binding properties of hCAP18/LL-37. Preferably, the agent is selected from the group consisting of short interfering RNA (siRNA) molecules, antisense oligonucleotides and compounds with binding affinity for hCAP18/LL-37. The invention further provides methods for inhibiting the proliferation of cancer cells in a patient, as well as methods and kits for diagnosing cancer.
