This study describes the distribution and the coexpression of specific neurochemical markers in both neuroendocrine‐like cells (NEC‐like) and polymorphous granular cells (PGCs) that populate the mucociliated epithelium of the lung in the air‐breathing fish Polypterus senegalus, using confocal immunohistochemistry. Using confocal immunohistochemistry, we determined the coexpression of specific neurochemical markers. Colocalization studies showed that 5HT is coexpressed with calbindin and nNOS and choline acetyltransferase (ChAT) is coexpressed with nNOS in the PGCs. This study also shows for the first time the simultaneous occurrence of piscidin 1 and 5HT in the PGCs. The function of these cells being equivalent to ones found in fish gill subepithelial parenchyma is still not known. Due to the importance of piscidin 1 in local immune defence, more research is to be useful to understand a possible interaction of PGCs with immune response in the bichir lung. In fact, the capacity of PGCs to produce NO and other neuroactive substances found in immune cells of fish may represent a primitive form of immunoregulation of innate immunity and specifically antimicrobial function as NO induction and respiratory burst activity are correlated with immune response. 相似文献

This paper reexamines the gill morphometrics of 20 European teleosts first reported in the early gill literature by Byczkowska-Smyk
and colleagues in attempt to clarify the long-recognized discrepancies between these data and those obtained in subsequent
works. Determination of gill dimensions for the pikeperch, Sander lucioperca, in this study (a species for which Byczkowska-Smyk reported data), along with a literature review for other European teleosts,
reveals inaccurate estimation of the total gill surface area by up to 18× for 19 of the 20 species reexamined. This error
results primarily from imprecise determination of the bilateral surface area of individual gill lamellae and, to a lesser
extent, the incorrect assumption that lamellar area and frequency are species-specific constants that do not vary with fish
body mass. This review compiles gill morphometric data from various sources to be used in place of the inaccurate gill area
estimates of Byczkowska-Smyk and colleagues and thereby clears the way for higher resolution in the comparative analysis of
gill morphology and its correlation to fish habitat and life history characteristics. 相似文献
