Abstract

The teleost brain is very complex and consists in several parts some of them different from the tetrapods. During their separate evolution, these fishes have acquired a particular structure of the brain, several parts of which have different shape or have no equivalent in tetrapod vertebrates (Kalam,1998). The studies on teleost fishes astroglia are still relatively scarce. In teleosts brain, however, the astroglial structures are represented mostly by ependymal tanycytes and radial glia (Lara et al., 1989; Maggs and Scholes,1990; Manso et al., 1997), but also by astrocytes (Kalaman, 1998; Arochena et al., 2004). This paper report the study on the astroglial architecture in the brain of a teleost fish, Diplodus sargus, by the immunohistochemical staining of GFAP (glial fibrillary acidic protein). GFAP is the main component of gliofilaments and is a reliable marker of all astroglial cells. GFAP shows also a considerable stability in its antigenic characteristics across vertebrates phylogeny (Nielsen and Jorgensen, 2003). The immunodetection of GFAP(+) structures shows in the sargus brain the presence of an astroglial architecture various and complex. It is represented mainly by fibres, which are more numerous and large in the mesencephalon and rhombencephalon, but very scarce in the telencephalon. Diplodus sargus astroglia is however similar to that reported in the carp (Kalaman, 1998) and grey mullet (Arochena et al., 2004) brains.
