Gaucher disease is the most prevalent lysosomal storage disease and it results from inherited deficient glucocerebrosidase activity. The glucocerebrosidase gene from normal people was sequenced by several laboratories and it was noted that a G or A nucleotide may be present at cDNA position 1601, resulting in 495arginine or 495histidine in the glucocerebrosidase polypeptide. In order to rule ou...

Gaucher disease is an autosomal recessive disorder, characterized by decreased levels of the lysosomal enzyme glucocerebrosidase. This deficiency results in a decreased breakdown of this glycosphingolipid glucocerebroside, which accumulates in the lysosomes of the monocyte-macrophage system. It is the most common form of sphingolipidosis. Clinically, the principle signs of Gaucher's disease are...

BACKGOUND Pain is one of the most disabling symptoms of Gaucher disease. It is referred by the majority of Gaucher patients and often persists despite long-term enzyme replacement treatment. It has been mainly considered as nociceptive pain secondary to skeletal involvement but it is described even in the absence of bone disease without a clear explanation. In the last years an increasing numbe...

Gaucher disease, the inherited deficiency of lysosomal glucocerebrosidase, is characterized by the presence of glucosylcer-amide macrophages, the accumulation of glucosylceramide in lysosomes and the secretion of inflammatory cytokines. However, the connection between this lysosomal storage and inflammation is not clear. Studying macrophages derived from peripheral monocytes from patients with ...

Gaucher’s disease is a Phenotypically heterogenous autosomal recessively inherited lysosomal storage disease, resulting from deficient activity of the enzyme glucocerebrosidase (GCase, acid β-glucosidase) due to mutations in GBA1. It is the most common amongst the various disorders classified under the lysosomal storage diseases. It is estimated that approximately 1 in 40,00060,000 persons in t...

Gaucher disease is an autosomal recessive lysosomal storage disorder caused by the deficient activity of glucocerebrosidase. Accumulation of glucosylceramide, primarily in the lysosomes of cells of the reticuloendothelial system, leads to hepatosplenomegaly, anemia and skeletal lesions in type I disease, and neurologic manifestations in types II and III disease. We report herein the identificat...

A case of acute lymphoblastic leukaemia, associated with cells resembling Gaucher cells in the bone marrow, is reported. The patient had no evidence of inherited Gaucher's disease and the ultrastructural appearance of the cells was consistent with pseudo-Gaucher cells described in other haematological diseases. This is the first report of these cells in association with acute lymphoblastic leuk...

Gaucher disease is a common lysosomal storage disease caused by a defect of acid -glucosidase (GCase). The optimal in vitro hydrolase activity of GCase requires saposin C, an activator protein that derives from a precursor, prosaposin. To develop additional models of Gaucher disease and to test in vivo effects of saposin deficiencies, mice expressing low levels (4–45% of wild type) of prosaposi...
