Brains from subjects who have Alzheimer's disease (AD) express inducible nitric oxide synthase (iNOS). We tested the hypothesis that iNOS contributes to AD pathogenesis. Immunoreactive iNOS was detected in brains of mice with AD-like disease resulting from transgenic expression of mutant human beta-amyloid precursor protein (hAPP) and presenilin-1 (hPS1). We bred hAPP-, hPS1-double transgenic m...

Hermansky-Pudlak syndrome (HPS) is a disorder of organelle biogenesis affecting 3 related organelles-melanosomes, platelet dense bodies, and lysosomes. Four genes causing HPS in humans (HPS1-HPS4) are known, and at least 15 nonallelic mutations cause HPS in the mouse. Where their functions are known, the HPS-associated proteins are involved in some aspect of intracellular vesicular trafficking,...

Hermansky-Pudlak syndrome (HPS), a disorder of organelle biogenesis, affects lysosomes, melanosomes, and platelet dense bodies. Seven genes cause HPS in humans (HPS1-HPS7) and at least 15 nonallelic mutations cause HPS in mice. Where their function is known, the HPS proteins participate in protein trafficking and vesicle docking/fusion events during organelle biogenesis. HPS-associated genes pa...

Hermansky-Pudlak syndrome (HPS) is an autosomal recessive condition characterized by a bleeding diathesis and hypopigmentation of the skin, hair, and eyes. Some HPS patients develop other complications such as granulomatous colitis and/or fatal pulmonary fibrosis. Eight genes have been associated with this condition, resulting in subtypes HPS-1 through HPS-8. The HPS gene products are involved ...

Hermansky-Pudlak syndrome (HPS) is a human disease characterized by partial loss of pigmentation and impaired blood clotting. These symptoms are caused by defects in the biogenesis of melanosomes and platelet dense granules, often referred to as lysosome-related organelles. Genes mutated in HPS encode subunits of the biogenesis of lysosome-related organelles complexes (BLOCs). BLOC-1 and BLOC-2...

Hermansky-Pudlak syndrome (HPS) is a rare autosomal recessive disorder characterized by oculocutaneous albinism and platelet dysfunction. A subset of patients also show ceroid deposition, which can result in pulmonary fibrosis or granulomatous colitis. Whether this colitis may be considered Crohn's disease is under debate. We report a case of a patient with HPS associated with inflammatory bowe...
