Leukocyte Imbalances in Mucopolysaccharidoses Patients
Lopes, Nuno; Maia, Maria L.; Pereira, Cátia S.; Mondragão-Rodrigues, Inês; Martins, Esmeralda; Ribeiro, Rosa; Gaspar, Ana; Aguiar, PatrícioMucopolysaccharidoses (MPSs) are rare inherited lysosomal storage diseases (LSDs) caused by deficient activity in one of the enzymes responsible for glycosaminoglycans lysosomal degradation. MPS II is caused by pathogenic mutations in the IDS gene, leading to deficient activity of the enzyme iduronate-2-sulfatase, which causes dermatan and heparan sulfate storage in the lysosomes. In MPS VI, there is dermatan s...
The Biology of Lysosomes: From Order to Disorder
Amaral, Olga; Martins, Mariana; Oliveira, Ana Rita; Duarte, Ana Joana; Mondragão-Rodrigues, Inês; Macedo, M. FatimaSince its discovery in 1955, the understanding of the lysosome has continuously increased. Once considered a mere waste removal system, the lysosome is now recognised as a highly crucial cellular component for signalling and energy metabolism. This notable evolution raises the need for a summarized review of the lysosome’s biology. As such, throughout this article, we will be compiling the current knowledge reg...
