✦ Synopsis


Vasoactive intestinal peptide (VIP) is a regulatory neuropeptide involved in a wide variety of functions, among them vasodilation, smooth muscle relaxation, sweat secretion, gastrointestinal peristalsis, and pancreatic function. A deficient VIP-innervation of sweat glands was recently described as a possible pathogenic factor in sweating of cystic fibrosis (CF) patients. To investigate a possible role for a defective VIP-gene in cystic fibrosis, we have used a panel of rodent-human hybrid cells, retaining defined complements of human chromosomes to localize the VIP-gene to the human chromosome region 6p21----6qter. As the CF gene was recently mapped to chromosome 7, we conclude that the VIP-gene is not the primary gene defect in this disease.

## Abstract A panel of mouse × human B‐and T‐cell hybrids was analyzed for the expression of MC56 determinant which marks the drug‐sensitive state of CEM cells. Karyotypic and phenotypic analyses of the tested clones showed that the expression of MC56 determinant correlated to the presence of human
