Schistosomiasis: proline production and release by ova.

Ní féidir ach le húsáideoirí cláraithe ailt a aistriú
Logáil Isteach / Cláraigh
The production and release of proline was measured in cleaned ova of Schistosoma mansoni. Proline was found to be released at approximately 76 mumoles/100 cc of ova water/hr. This high rate of proline production was found to correlate with extremely active proline synthetic enzymes in the ova.

Proline trapping in granulomas, the site of collagen biosynthesis in murine schistosomiasis.

Proline, a critical substrate for collagen synthesis, is increased in liver undergoing fibrosis. In mice with schistosomiasis, the incorporation of proline into collagen occurs within liver granulomas. To study the interaction of liver cells and granulomas in the development of fibrosis, we assayed

We determined collagen synthetic rates and utilization of key amino acid precursors of collagen in slices of wedge liver biopsy specimens obtained at required surgery from 9 patients with hepatosplenic schistosomiasis and from 4 control patients. The liver specimens from the patients with
Schistosomiasis mansoni disseminated worm eggs in mice and humans induce granulomatous inflammations and cumulative fibrosis causing morbidity and possibly mortality. In this study, intrahepatic and I.V. injections of a double-stranded oligodeoxynucleotide decoy containing the TGF-beta regulatory

The concentration of L-hydroxyproline in the liver of ICR female mice increased rapidly during the 8th to 11th weeks of Schistosoma mansoni infection. Free L-proline concentration began to increase about the 7th week and reached its maximum at the 8th to 9th weeks of the infection, when the

Liver collagen synthesis in murine schistosomiasis.

Collagen synthesis was measured in liver slices obtained from mice with hepatosplenic schistosomiasis. Enlarged fibrotic livers from these mice contained 20 times more collagen than normal. This model of hepatic fibrosis results from an inflammatory granulomatous host response to Schistosoma mansoni

Parasitological, pathological and functional studies on the effects of IFN alpha 2b in murine hepatic schistosomiasis.

The effects of different doses of Interferon alpha 2b (IFN alpha 2b), alone and in combination with praziquantel (PZQ), on hepatic schistosomiasis were tested. An experimental murine model of hepatic schistosomiasis was used. Four parameters were assessed; hepatic fibrosis by estimation of

The activity of procollagen prolyl hydroxylase was measured in fibrotic liver obtained from mice with hepatosplenic schistosomiasis, an animal model of the most prevalent form of human liver fibrosis. Measurable activity of prolyl hydroxylase in fibrotic liver supernatants was 47-fold higher than

Colchicine, an antimicrotubular agent, was shown to block the transcellular movement of certain structural macromolecules such as collagen. In the present study, the effect of colchicine on collagen synthesis and secretion by monolayer cultures of fibroblasts from livers of mice infected with

Primary cell cultures from the livers of mice infected with Schistosoma mansoni were prepared and cells with the appearance of fibroblasts by light microscopy were isolated. Collagen synthesis was estimated by measuring incorporation of 14C-proline into collagenase-sensitive proteins for both

We have previously shown that co-culture of T cell enriched spleen lymphocytes can reduce collagen synthesis and stimulate proliferative activity by liver fibroblasts from S. mansoni infected mice. The present study examines which subset of T cells is responsible for this modulation. Co-culture of
Schistosomiasis is a destructive parasitic zoonosis caused by agents of the genus Schistosoma, which afflicts more than 250 million people worldwide. The freshwater amphibious snail Oncomelania hupensis serves as the obligate intermediate host of Schistosoma japonicum. Macrophage migration

We previously have shown [Takahashi & Kobayashi (1982) Hepatology 2, 249-254] that the administration of concanavalin A to mice with schistosomiasis caused liver collagen content to be reduced by 50%. Here we report the effects of concanavalin A and aggregated mouse myeloma IgG on liver lysyl
