Proterospores are formed exclusively at the beginning of the sporulation period and independently of abiotic factors. They differ both morphologically and physiologically from other spores developed later by the same fruit-body. As seen inGanoderma, proterospores germinate readily, whereas other spores must first pass through a fly larva gut. These proterospores are therefore well adapted to dispersal by air, the other spores, however, to dispersal by animals. In this respect, ontogenesis appears to recapitulate phylogeny. A comparative study of proterospores should further clarify systematic relationships within the fungi. 相似文献

To investigate and analyze induction of phenotypic and functional maturation of murine DCs by GLP. Both phenotypic and functional activities were assessed with use of conventional scanning electronic microscopy (SEM) for the morphology of the DCs, transmitted electron microscopy (TEM) for intracellular lysosomes inside the DC, cellular immunohistochemistry for phagocytosis by the DCs, flow cytometry (FCM) for the changes in key surface molecules, bio-assay for the activity of acid phosphatases (ACP), and ELISA for the production of pro-inflammatory cytokine IL-12. It was found that GLP induced phenotypic maturation, as evidenced by increased expression of CD86, CD40, and MHC II. Functional experiments showed the down-regulation of ACP inside the DCs, which occurs when phagocytosis of DCs decreased, and antigen presentation increased with maturation. Finally, GLP increased the production of IL-12.These data reveals that GLP promotes effective activation of murine DCs. This adjuvant-like activity may have therapeutic applications in clinical settings that require a boosting of the immune response. Therefore concluded that GLP can exert positive induction to murine DCs at the used concentration. 相似文献

Responses of mycelia ofGanoderma lucidum to vanadium, selenium and germanium were examined over a wide range of concentrations (10–1, 120 μg/ml) in pure culture.
Se and V were found to be highly toxic, but Ge was not toxic at the levels tested.Ganododerma lucidum cultivated on substrates of sawdust with V (30–80 μg/g) developed mature fruitbodies, but the bioaccumulation of V was quite
low (2.5–7 μg/g in pileus, 12.5–21.5 μg/g in stipe and <1 μg/g in basidiospores). Se as Na2SeO4 labeled with75Se was effectively taken up from substrates and accumulated in fruitbodies (mainly in pileus), then depleted by discharge
of basidiospores. Ge as GeCl4 labeled with77Ge was easily uptaken and translocated into fruitbodies. 相似文献
