Differentation of the fat body cells in the precocius adults of Schistocerca gregaria: regulation of polyploidy by juvenile hormone

Kooman, C. J; Nair, K. K.
Mem. Inst. Oswaldo Cruz; 82 (supl.3), 1987
Precocious adults from 2nd and 3rd instar larvae of the desert locust Schistocerca gregaria were used to assess the competence of their fat body to synthesize DNA in response to a juvenile hormone analog (JHA), hydoprene. Autoradiographic studies show that JHA stimulates DNA synthesis since a significant...

Immunological aspects of host-schistosome relationships

Damian, Raymond T.
Mem. Inst. Oswaldo Cruz; 82 (supl.4), 1987
The complex immunological relationships between schistosomes and their vertebrate hosts are considered to be conveniently divisible into four distinct, though interrelated categories: the parasite's vulnerability to, its evasion of, and its exploitation of the host's immune response, and its stimulation ...

Cell-matrix interactions in Schistosomal portal fibrosis: a dynamic event

Grimaud, Jean-Alexis.
Mem. Inst. Oswaldo Cruz; 82 (supl.4), 1987
In recent years, one of the most significant progress in the understanding of liver diseases was the demonstration that liver fibrosis is a dynamic process resulting from a balance between synthesis and degradation of several matrix components, collagen in particular. Thus, fibrosis has been found to be ...
