Abstract
Lysosomes and lysosome related organelles (LROs) are dynamic organelles at the intersection of various pathways involved in maintaining cellular hemostasis and regulating cellular functions. Vesicle trafficking of lysosomes and LROs are critical to maintain their functions. The lysosomal trafficking regulator (LYST) is an elusive protein important for the regulation of membrane dynamics and intracellular trafficking of lysosomes and LROs. Mutations to the LYST gene result in Chédiak-Higashi syndrome, an autosomal recessive immunodeficiency characterized by defective granule exocytosis, cytotoxicity, etc. Despite eight decades passing since its initial discovery, a comprehensive understanding of LYST's function in cellular biology remains unresolved. Accumulating evidence suggests that dysregulation of LYST function also manifests in other disease states. Here, we review the available literature to consolidate available scientific endeavors in relation to LYST and discuss its relevance for immunomodulatory therapies, regenerative medicine and cancer applications.

Abstract
The 3beta-(2-diethylaminoethoxy)-androstenone HCl (U18666A), progesterone and several cationic amphiphilic drugs have been shown to alter the trafficking of a number of intracellular membrane proteins including CD63/Lamp-3, insulin growth factor 2/mannose 6-phosphate receptor (IGF2/MPR), and the Niemann-Pick C1 gene product (NPC1) as well as ganglioside GM1. We have examined the effects of these compounds on cultured melanocytes at concentrations that have been shown to effectively alter intracellular trafficking. Treatment of melanocytes with U18666A (2.5 micro M) or progesterone (15 micro M) for 96 h decreased melanin content an average of 67% as compared with control without lowering the total cellular tyrosinase activity. Steroidal alkaloids that preferentially act on the Sonic Hedgehog signaling pathway showed no related specificity in their ability to decrease pigmentation. In melanocytes treated with U18666A, tyrosinase accumulates in a compartment that contains both lysosome-associated membrane protein-1 (Lamp 1) and MPR, and stains with filipin, consistent with cholesterol-laden late endosomes/lysosomes. Our results suggest that tyrosinase, like the NPC1 gene product, traverses a U18666A-sensitive trafficking pathway.

Abstract
Chediak-Higashi Syndrome (CHS) is an autosomal recessive disorder that affects several species including mice, humans, and cattle. Evidence based on clinical characteristics and somatic cell genetics suggests that mutations in a common gene cause CHS in the three species. The CHS locus on human chromosome 1 and mouse chromosome 13 encodes a lysosomal trafficking regulator formerly known as LYST, now known as CHS1, and is defective in CHS patients and beige mice, respectively. We have mapped the CHS locus to the proximal region of bovine chromosome 28 by linkage analysis using microsatellite markers previously mapped to this chromosome. Furthermore, we have identified a missense A:T-->G:C mutation that results in replacement of a histidine with an arginine residue at codon 2015 of the CHS1 gene. This mutation is the most likely cause of CHS in Wagyu cattle. In addition, we describe quick, inexpensive, PCR based tests that will permit elimination of the CHS mutation from Wagyu breeding herds.

Abstract
Chediak-Higashi syndrome (CHS) is a rare, autosomal recessive disorder characterized by hypopigmentation, severe immunologic deficiency with neutropenia and lack of natural killer (NK) cells, a bleeding tendency and neurologic abnormalities. Most patients die in childhood. The CHS hallmark is the occurrence of giant inclusion bodies and organelles in a variety of cell types, and protein sorting defects into these organelles. Similar abnormalities occur in the beige mouse, the proposed model for human CHS. Two groups have recently reported the identification of the beige gene, however the two cDNAs were not at all similar. Here we describe the sequence of a human cDNA homologous to mouse beige, identify pathologic mutations and clarify the discrepancies of the previous reports. Analysis of the CHS polypeptide demonstrates that its modular architecture is similar to the yeast vacuolar sorting protein, VPS15.

Abstract
Fibroblasts from a beige mouse (C57BL/6J; bgJ bgJ) have been established and maintained in culture for more than 3 yr. At early passages, the mutant cells were distinguishable from C57BL/6J control mouse fibroblasts at the ultrastructural level by the presence of enlarged cytoplasmic granules. After continuous passaging, this distinguishing feature was lost from the mutant cells, correlated with their increased growth rate. Clustered, perinuclear distribution of lysosomes was retained, however, and was quantitatively different at any passage number of the beige cell line from the dispersed distribution of these organelles in control mouse fibroblasts, as analyzed by computer-aided, video-enhanced light microscopy. In somatic cell hybrids between the established beige cell line and a control human diploid fibroblast cell strain, seven uncorrected hybrid lines retained a lysosomal dispersion pattern statistically indistinguishable from that of the beige mouse cell lines. Three corrected hybrid lines had lysosomal dispersion patterns that were significantly different from the beige parent line and indistinguishable from that of the control mouse fibroblast line. Thus, lysosomal dispersion can be used objectively and quantitatively to distinguish mutant beige and control mouse fibroblasts and corrected vs. uncorrected cell hybrids made from the beige/control human somatic cell crosses.

Abstract
We report the first prenatal diagnosis of an affected fetus with Chediak-Higashi syndrome (CHS). Diagnosis was accomplished via fetal blood sampling at 17 menstrual weeks and was confirmed after birth. Retrospective measurement of the largest acid phosphatase-positive lysosomes in cultured amniotic fluid cells and chorionic villus cells showed that in CHS these lysosomes are significantly larger than those in normal cells. This method may be used for prenatal diagnosis of CHS by amniocentesis and chorionic villus sampling (CVS).

Abstract
The autosomal recessive disease Chediak-Higashi syndrome (CHS) is a progressive and generally fatal disease of humans. The underlying genetic defect in CHS is unknown and prenatal diagnostic methods have not been applied to this disease. The purpose of this study was to determine if CHS chorionic cells expressed a characteristic of CHS--enlarged lysosomes--that would permit the prenatal diagnosis of the disease. Cats with CHS, which have been shown to be homologous with human CHS, were used as the model system in this study. Chorionic tissue samples were obtained from CHS and control cat fetuses and cultures of cells were established. Acid phosphatase was utilized as a marker of lysosomes and cultures of chorionic fibroblasts from CHS and control fetuses were stained histochemically for acid phosphatase. The diameter of the largest lysosomes in 150 cells of each fetus was determined. The mean (+/- SD) diameter (in microns) of the largest lysosomes of normal fetuses was 0.9 +/- 0.13 (range 0.5-7.0 microns), whereas the mean diameter of lysosomes in CHS chorionic cells was 3.9 +/- 0.65 microns (range 0.5-25 microns). These means were significantly different (P less than 0.0001). These data suggest that it should be possible to diagnose human CHS in the first trimester by chorionic villus sampling.

Abstract
Chediak-Higashi syndrome (CHS) is an autosomal recessive disease in humans, cats, and 8 other species. The homology of CHS in humans and cats has been demonstrated. Since human CHS is a progressive, serious, and eventually fatal disease, a method for prenatal diagnosis would be desirable. This study was designed to determine whether CHS could be diagnosed prenatally by examination of amniotic fluid cells. The amniotic fluid samples were obtained from CHS and control cat fetuses on the 45th day of gestation and cultures of cells were established. Because the underlying enzyme deficiency in CHS has not been identified, it was necessary to use a secondary manifestation of the syndrome in these studies. The secondary manifestation used was the characteristic enlargement of lysosomes associated with the disease. The lysosomes of these cells were stained by acid phosphatase histochemistry and the diameter of the largest lysosome in each cell was measured by light microscopy with a calibrated ocular micrometer. The diameters of the largest lysosomes in cells of normal fetuses ranged from 0.5 to 7.0 micron (means ranged from 0.9 to 1.8 micron), whereas the diameter of the largest lysosomes in the cells of CHS fetuses ranged from 0.5 to 30 microns (means ranged from 6.4 to 12.8 microns). The approximate t-test for independent samples with unequal variances disclosed that the largest acid phosphatase-positive lysosomes in amniotic fluid cells of CHS cat fetuses were significantly larger than the lysosomes in the cells of normal cat fetuses (P less than 0.0001). This information should, by extrapolation, provide the basis for the prenatal diagnosis of human CHS by amniocentesis.

Abstract
Chediak-Higashi syndrome (CHS) is an autosomal recessive disease of humans, mink, cattle, mice, killer whales, cats, and blue and silver foxes. The disease is characterized by incomplete oculocutaneous albinism, recurrent and severe pyogenic infections, a bleeding tendency secondary to a platelet storage pool deficiency, and enlarged granules in many types of cells. Humans with CHS usually die during childhood. It has been suggested that the prenatal diagnosis of CHS should be possible by the demonstration of enlarged granules in neutrophils of fetal blood. We tested this hypothesis using 20 cat fetuses obtained 18 days at prepartum. Two litters (6 fetuses) were from CHS to CHS matings and four litters (14 fetuses) were from CHS male to heterozygous female matings. Fetuses were identified as CHS or phenotypically normal by histologic examination of the size of melanin granules in the ciliary body and by the size of periodic acid-Schiff-positive granules in renal tubular epithelial cells. The diameter of the peroxidase-positive granules in neutrophils of the 15 CHS fetuses ranged from 0.3 to 3.0 microns whereas those of the five normal fetuses ranged from 0.3 to 1.0 micron. All 20 fetuses were correctly classified as CHS or phenotypically normal. These data indicate that examination of the size of fetal blood neutrophil granules can be used to diagnose CHS prenatally.

Abstract
Although the autosomal recessive disease Chediak-Higashi syndrome (CHS) has been described in humans, cats, mink, cattle, mice, killer whales, blue foxes, and silver foxes, and these conditions appear quite similar, no direct evidence of the homology of this disease in the various species has been presented. To determine if CHS in humans, cats, mink, cattle, and mice is due to a mutant gene at the homologous genetic locus in each species, or alternatively, if these are merely similar syndromes, genetic complementation analysis after interspecific somatic cell (fibroblast) hybridization was performed. "Paracrystal" formation was the criterion used for the determination of complementation. The initial studies in this report were designed to characterize paracrystal formation in control and CHS fibroblasts of these five species. Most of the control fibroblasts from each species (91-96.6%) formed paracrystals upon incubation with 25 micrograms/ml of the microtubule depolymerizing agent vinblastine sulfate. A significantly (P less than 0.05) smaller percentage of the CHS fibroblasts formed paracrystals after the same incubation (except CHS mice, with 90.2% paracrystals). It was found that 52% of the human CHS fibroblasts, 60% of cat CHS fibroblasts, 47% of mink CHS fibroblasts, and 53.8% of cow CHS fibroblasts formed paracrystals. For genetic complementation analysis, human CHS fibroblasts were fused to cat, mink, cow, or mouse CHS fibroblasts with polyethylene glycol. Control fusions were human CHS fibroblasts fused with human, cat, mink, cow, and mouse normal fibroblasts. The results of complementation analysis after the fusion of human CHS with cow CHS and human CHS with mouse CHS fibroblasts were inconclusive. A lack of complementation of human CHS with cat CHS and human CHS with mink CHS fibroblasts indicates that the disease is homologous in these species.
