Associations of Lamp2 with chemical compounds

  • The LAMP-1/2 double-deficient cells and, to a lesser extent, LAMP-2 single-deficient cells showed an accumulation of unesterified cholesterol in endo/lysosomal, rab7, and NPC1 positive compartments as well as reduced amounts of lipid droplets [12].
  • In these type I and type II granules, MHC class II molecules, mannose-6-phosphate receptors and lysosomal membrane proteins (lamp1 and lamp2) localize to small intralumenal vesicles [15].
  • The increased level and glycosylation of both LAMP-1 and LAMP-2 was observed also in cells treated with a synthetic chalcone carboxylic acid analog of RA and by combination of either retinoid with dibutyryl cyclic AMP [1].
  • There was no increase in large polylactosaminoglycans of lamp-1 and lamp-2 after retinoic acid treatment, but an increase in the size of small polylactosaminoglycans (included on Bio-Gel P-6) and tri- and tetra-antennary complex oligosaccharides [16].
  • The phagosomes containing live M. ptb and M. avium were significantly reduced in their ability to acquire some markers for the endocytic pathway, such as internalized calcein, BSA-gold or the membrane protein Lamp 2 [17].
