Article: Evidence for intercellular coupling and connexin-like protein in the luminescent endoderm of Renilla koellikeri (Cnidaria, Anthozoa).

Introduction

Gap junction channels are recognized as important pathways for intercellular communication subserving electrical and metabolic coupling in metazoan tissues (Paul, 1995). The wide range of roles attributed to gap junctions - maintenance of homeostasis, mediation of hormonal responses, and coordination of cellular activities in epithelial and neural conduction as well as in development - is reflected in the wide distribution of these channels among metazoan phyla (Revel, 1988). Within the phylum Cnidaria, however, gap junctions were reported to be abundant in the Hydrozoa, but absent in the Scyphozoa and the Anthozoa (Mackie et al., 1984). Because ...
