These results support the notion that HOPS might result from the reversible association of functionally distinct subcomplexes. Another possibility, however, is that a pool of unassembled snapin exists and is physiologically important. Further studies will be required to elucidate this point. Recently, elegant studies by Peden and colleagues 28 provided strong evidence for the latter. Likewise, initial characterization of mammalian HOPS subunits was focused on their localization to late endosomes and lysosomes and interaction with syntaxin 7, a SNARE protein implicated in late endosome—lysosome and lysosome—lysosome fusion Overexpression of Vps39 and Vps18 elicited abnormal perinuclear aggregation of late endosomes and lysosomes, while knockdown of Vps18 by siRNA treatment resulted in dispersion of these organelles throughout the cell periphery 36 , Hence, there seems to be consensus that HOPS functions as a tethering factor regulating SNARE complex formation and that it can act at several steps along the endocytic pathway.
There was a biological inflammatory syndrome. The bacteriological examinations of the bronchial expectorations were negative. The chest CT showed bilateral alveolar opacities at the upper, with attraction of the fissures, without nodes. The bronchoscopy showed anomalies of the bronchial mucous membrane in 2 superior lobes.
The perendoscopiques biopsies confirmed a MALT lung lymphoma. We did not find other localizations. Chemotherapy was proposed to our patient with favorable evolution.
The MALT primary lung lymphoma must not be underestimated. Clinical manifestations and radiological characteristics are no specific and it's necessary to eliminate a lung cancer or tuberculosis in our countries.
The difficulties of their diagnostic are intensified by the not availability of an adequate technical tray. Therefore, it is possible that variations in subunit composition could contribute to the observed functional diversity of mammalian HOPS. It is clear that further investigation will be necessary to ascertain the functions of these three complexes.
Rab38 Rab38 was identified as the product of a gene that is predominantly expressed in pigmented melanocytes and retinal pigment epithelium cells, although expression in other cell types was also documented 12 , The chocolate mouse is considered a phenocopy of the brown mouse mutated in the gene encoding the TYRP1 protein involved in melanin biosynthesis, suggesting that Rab38 might be required for normal trafficking of TYRP1 to maturing melanosomes.
Nevertheless, additional work is necessary to establish the exact function of Rab Although both Vps33a and its paralog, Vps33b, are widely expressed in mammalian tissues, genetic evidence indicates that they play nonredundant functions.
Interestingly, platelet function seems to be compromised also in ARC syndrome, although this could be due to deficiencies in organelles other than platelet dense granules e. Furthermore, immunohistochemical staining of the dysbindin protein in postmortem human brain revealed reduced dysbindin levels at hippocampal formation sites of schizophrenic brain samples relative to matched controls While links to both muscular dystrophy and schizophrenia are very exciting, the fact that the only patient known to carry a mutation in the dysbindin coding region the nonsense mutation QX was reported to suffer from HPS with no serious muscular or neurological abnormalities at 48 years of age should not be overlooked Conclusions Following the identification of a number of genes associated with HPS, work by several groups have begun to shed light onto the cell biology underlying this disease.
However, a number of fundamental questions remain unanswered. To address these and other issues related to HPS, cell biologists are expected to play a major role.
