Lysosomal exocytosis and lipid storage disorders.
Lysosomes are acidic compartments in mammalian cells that are primarily responsible for the breakdown of endocytic and autophagic substrates such as membranes, proteins, and lipids into their basic building blocks. Lysosomal storage diseases (LSDs) are a group of metabolic disorders caused by genetic mutations in lysosomal hydrolases required for catabolic degradation, mutations in lysosomal me...
متن کاملLysosomal Storage Disorders and Malignancy
Lysosomal storage disorders (LSDs) are infrequent to rare conditions caused by mutations that lead to a disruption in the usual sequential degradation of macromolecules or their transit within the cell. Gaucher disease (GD), a lipidosis, is among the most common LSD, with an estimated incidence of 1 in 40,000 among the Caucasian, non-Jewish population. Studies have indicated an increased freque...
متن کاملLipid storage disorders block lysosomal trafficking by inhibiting a TRP channel and lysosomal calcium release.
Lysosomal lipid accumulation, defects in membrane trafficking and altered Ca(2+) homoeostasis are common features in many lysosomal storage diseases. Mucolipin transient receptor potential channel 1 (TRPML1) is the principle Ca(2+) channel in the lysosome. Here we show that TRPML1-mediated lysosomal Ca(2+) release, measured using a genetically encoded Ca(2+) indicator (GCaMP3) attached directly...
متن کاملImmunochemistry of lysosomal storage disorders.
BACKGROUND Lysosomal storage disorders are a group of genetic diseases, each with a broad spectrum of clinical presentation that ranges from attenuated to severe. The immunochemical analysis of patient samples is aimed at several key aspects of patient management, including early detection of the disorder, prediction of clinical severity, determining the most appropriate therapeutic regimen, an...
متن کاملTreatments for lysosomal storage disorders.
There are over 70 human diseases that are caused by defects in various aspects of lysosomal function. Until 20 years ago, the only specific therapy available for lysosomal storage disorders was allogeneic haemopoietic stem cell transplantation. Over the last two decades, there has been remarkable progress and there are now licensed treatments for seven of these diseases. In some cases, a choice...
