## Abstract

Nucleic acid sequences which encode biologically active ETF, expression vectors which direct the expression of ETF, ETF polypeptides, antibodies which specifically bind ETF and processes for preparing the same are disclosed. Also disclosed are methods for treating or preventing gastrointestinal diseases and HIV or HIV-associated diseases.

## Claims

### Claim 1

A method for treating or preventing gastrointestinal diseases, comprising administering to a patient a therapeutically effective amount of epithelium-derived T-cell factor polypeptide, wherein said polypeptide is selected from the group consisting of:
(a) a polypeptide comprising the amino acid sequence of SEQ ID NO 3;
(b) a polypeptide comprising the amino acid sequence of SEQ ID NO 6; and
(c) a polypeptide encoded by an isolated nucleic acid selected from the group consisting of:
(i) DNA comprising nucleotides 145 through 486 of the DNA sequence of SEQ ID NOS 1 or 4;
(ii) DNA that hybridizes to the DNA of (i) or their complementary strands under conditions of high stringency and upon expression encode mammalian epithelium-derived T-cell factor; and
(iii) DNA that, due to degeneracy of the genetic code, encodes a polypeptide encoded by any of the foregoing DNA.

### Claim 2 (depends on 1)

The method according to claim 1 wherein said gastrointestinal disease is chemo- or radiation-induced enteritis.

### Claim 3 (depends on 1)

The method according to claim 1 wherein said epithelium-deprived T-cell factor polypeptide comprises the amino acid sequence of SEQ ID NO 3.

### Claim 4 (depends on 1)

The method according to claim 1 wherein said epithelium-derived T-cell factor polypeptide comprises the amino acid sequence of SEQ ID NO 6.

### Claim 5 (depends on 1)

The method according to claim 1 wherein said epithelium-derived T-cell factor polypeptide is contained within a diluent or carrier.
