Lung-Restricted Macrophage Activation in the Pearl Mouse Model of Hermansky-Pudlak Syndrome

Lung-restricted macrophage activation in the pearl mouse model of Hermansky-Pudlak syndrome.

Pulmonary inflammation, abnormalities in alveolar type II cell and macrophage morphology, and pulmonary fibrosis are features of Hermansky-Pudlak Syndrome (HPS). We used the naturally occurring "pearl" HPS2 mouse model to investigate the mechanisms of lung inflammation observed in HPS. Although baseline bronchoalveolar lavage (BAL) cell counts and differentials were similar in pearl and strain-...

Hermansky-Pudlak syndrome.

We present a rare disease condition Hermansky-Pudlak syndrome in a 33-year-old male. He was born of a consanguineous marriage, had occulo-cutaneous albinism, nystagmus, decreased visual acuity, refractory errors, pulmonary fibrosis and granulomatous inflammation of the colon. In spite of all the classical features of this genetic disorder he was labeled to have disseminated tuberculous infectio...

Hermansky-Pudlak Syndrome

Hermansky-Pudlak syndrome.

A 55-year-old man had oculocutaneous albinism and a history of frequent bruising following minimal trauma. The simultaneous occurrence of these features was first described by Hermansky and Pudlak in 1959. The Hermansky-Pudlak syndrome follows an autosomal recessive trait and is most frequently found in Puerto Rico and in the Swiss alps. It consists of the triad phenotype of hypopigmentation, p...

Hermansky-Pudlak syndrome

Inherited platelet function disorders (IPFDs) encompass a heterogeneous group of haemorrhagic diseases caused by congenital defects of platelets function affecting various elements of the platelet physiology (membrane receptors, intraplatelet signalling proteins, granules), and leading to different clinical manifestations (1–3). Platelets have three types of secretory granules that differ in th...
