 * LRO is lysosome related organelles, which are lysosome - like organelles that have membrane parameters of lysosomes and some of their enzymes, but only residual or zero degradation activity unlike lysosomes.


 * These organelles include:
 * Azurophilic granules of eosinophilic and neutrophilic granulocytes, the disorders o which lead, among other things, to intestinal diseases.
 * Melanosomes of melanocytes whose deficiency leads to a certain type of albinism
 * Delta granules of platelets, the disorder of which leads to increased bleeding
 * Lytic granule of NK cells and Tc lymphocytes, the disorder of which leads to immunodeficiency
 * Secondary granule of pneumocytes II. whose disorder leads to pulmonary fibrosis
 * Osteoclast lysosomes


 * Syndromes with LRO include Chediak-Higashi syndrome and Hermansky-Pudlak syndrome.
