Abstract

The present application describes peptides that stimulate arachidonic acid release in target cells. The application also discloses peptides that cause intracellular calcium release. The application also discloses methods of using the disclosed peptides.

Claims (9)

1. A polypeptide, which is 6 to about 20 amino acids in length, and which consists of or comprises the peptide of SEQ ID NO:29.

2. The polypeptide according to claim 1 , which is 6 to about 15 amino acids long.

3. The polypeptide according to claim 2 , which is 6 to about 10 amino acids long.

4. The polypeptide according to claim 3 , which is 6 to about 7 amino acids long.

5. The polypeptide according to claim 4 , which is 6 amino acids long.

6. A method of inducing production of arachidonic acid in a target leukocyte or phagocyte cell comprising contacting the target cell with the polypeptide of claim 1 .

7. A method of activating cPLA 2 in a target leukocyte or phagocyte cell comprising contacting the target cell with the polypeptide according to claim 1 , wherein said activating of cPLA 2 is detected by measuring production of arachidonic acid.

8. A method of producing superoxide in a target leukocyte or phagocyte cell comprising contacting the cell with the polypeptide according to claim 1 .

9. A method of causing movement of a cultured target cell, comprising contacting the cultured target cell with the polypeptide according to claim 1 .
