We investigated the binding of the gp120 glycoprotein of the human immunodeficiency virus (HIV-1) to neural glycolipids and glycoproteins by ELISA. The gp120 protein bound to sulfatide (GalS), a sulfated glycolipid autoantigen implicated in sensory neuritis, and to the myelin associated glycoprotein (MAG), an autoantigen in demyelinating neuropathy. Binding of gp120 to MAG was inhibited by the HNK-1 antibody, which recognizes a sulfated glucuronic acid epitope, suggesting that the interaction involves carbohydrate determinants. Sulfatide and MAG are potential receptors for gp120 in peripheral nerve and may have a role in the neuropathy associated with HIV-1 infection.

The effect of galactocerebroside 3'-sulfate (sulfatide) or cholesterol sulfate on syncytium formation induced by bovine immunodeficiency virus (BIV)-infected cells was investigated in vitro. Sulfatide was purified from bovine brain and incorporated in liposomes which were composed of egg phosphatidylcholine (PC), cholesterol (Chol), and dipalmitoylphosphatidic acid (DPPA). Either sulfatide- or cholesterol sulfate-containing liposomes effectively prevented syncytium formation induced by BIV-infected cells, but the inhibitory effect of sulfatide alone on syncytium formation was low. On the other hand, neither liposomes containing galactocerebroside nor liposomes composed of egg PC, Chol, and DPPA had any effect on syncytium formation induced by BIV-infected cells. These results suggest that liposomes containing sulfatide or cholesterol sulfate are an efficient agent to inhibit syncytium formation induced by BIV-infected cells, and that sulfate residue might play an important role in the inhibition of syncytium formation.

Sulfatide is 3-O-sulfogalactosylceramide that is synthesized by two transferases (ceramide galactosyltransferase and cerebroside sulfotransferase) from ceramide and is specifically degraded by a sulfatase (arylsulfatase A). Sulfatide is a multifunctional molecule for various biological fields including the nervous system, insulin secretion, immune system, hemostasis/thrombosis, bacterial infection, and virus infection. Therefore, abnormal metabolism or expression change of sulfatide could cause various diseases. Here, we discuss the important biological roles of sulfatide in the nervous system, insulin secretion, immune system, hemostasis/thrombosis, cancer, and microbial infections including human immunodeficiency virus and influenza A virus. Our review will be helpful to achieve a comprehensive understanding of sulfatide, which serves as a fundamental target of prevention of and therapy for nervous disorders, diabetes mellitus, immunological diseases, cancer, and infectious diseases.
