The present disclosure provides novel peptides that having immunomodulatory activities in vitro and in vivo. The peptides can include a particular striapathic region of alternating hydrophilic and hydrophobic modules that can adopt an amphipathic conformation under physiological conditions. This disclosure provides peptides that can specifically bind to key functional regions on one or more signaling proteins, particularly pro-inflammatory cytokines, macrophage inhibition proteins, and histone regulation proteins. This disclosure includes peptides that are sufficiently stable in the circulation to allow for intravenous administration. Pharmaceutical compositions including the subject peptides are also provided. The subject peptides find use in methods of modulating macrophage activity. In some cases, the peptide is a CD206-binding agent. Also provided are methods of treating a subject for a condition associated with chronic inflammation using the peptides and compositions of this disclosure.

Peptides having immunomodulatory properties

Aspects of the present invention relate to peptides having anti-inflammatory activity, compositions containing one or more of the peptides, and use of the peptides to treat conditions associated with excessive inflammation in animals, particularly humans and other mammals.

Peptides having anti-inflammatory properties

Methods for treating a subject for pancreatic cancer via administration of small anti-inflammatory peptides are disclosed. The peptides may be administered in conjunction with another therapeutic agent, such as a chemotherapeutic agent, or therapeutic regimen. In some cases, the anti-inflammatory peptide that finds use in the subject methods has the amino acid sequence Lys-Phe-Arg-Lys-Ala-Phe-Lys-Arg-Phe-Phe (SEQ ID NO:1) or a multimer, derivative, or variant thereof.

Peptide-based methods for treating pancreatic cancer

Lytic peptides, including fusion peptides of lytic peptides conjugated with luteinizing hormone-releasing hormone or modified versions thereof to target luteinizing hormone-releasing hormone receptors, are disclosed. The lytic peptides show anti-proliferative activity against human prostate cancer cell lines, but are nontoxic to normal primary human prostate epithelial cells or to bone marrow stromal cells in co-culture. The lytic peptides have specificity for and anti-proliferative activity against prostate cancer tumor cells, and low toxicity for normal prostate cells, making the peptides useful in therapies for prostate cancer.
