From: Role of lysosomes in physiological activities, diseases, and therapy
Diseases | Lysosomal dysfunction | Outcomes | Reference |
---|---|---|---|
Atherosclerosis | Lysosomal acid lipase deficient | Substantial decrease in lysosomal acid lipase activity leads to premature atherosclerosis in human | [57] |
OxLDL or cholesterol crystal accumulation | OxLDL or cholesterol crystal causes lysosomal membrane permeability, autophagy deficient, mitochondrial dysfunction, inflammasome activation, and apoptosis | ||
Neurodegeneration diseases | |||
Alzheimer's disease | Presenilin 1 mutation | Defective Presenilin 1-dependent lysosomal acidification is one of the main causes of early-onset familial AD | |
Becn1 ablation | Heterozygous deletion of beclin 1 (Becn1) results in autophagy disruption, Aβ deposition, and neurodegeneration | [97] | |
Cathepsin D mutation | The T-allele of cathepsin D rs17571 increases risk of AD | [92] | |
Cathepsin B ablation | Ablation of cathepsin B increases the abundance of Aβ42 and potentiates plaque deposition | [91] | |
Parkinson’s disease | Snca mutation | A53T point mutation in the Snca gene causes familial PD | |
Atp13a2 ablation | Atp13a2 depletion leads to lysosomal membrane instability, impaired acidification, blocked clearance of autophagosomes, α-syn accumulation, and cell death | ||
Gba1 mutation | Mutations in the Gba1 gene are important risk factors for PD | [113] | |
Huntington disease | Htt mutation | Mutated HTT protein has abnormally long polyglutamine (polyQ) repeats near the N-terminus, which promotes formation of toxic oligomers and neuronal inclusion bodies | |
Wdfy3 ablation | Depletion of Wdfy3 accelerates the accumulation of polyQ aggregates | [127] | |
Sqstm1 knockdown | Sqstm1 knockdown increases mHTT-induced cell death | [128] | |
Pancreatitis | Impaired autophagy flux | Increased autophagosome formation and decreased autophagosome clearance are observed | |
Imbalanced cathepsin B and cathepsin L | Imbalance between cathepsin B and cathepain L contributes to accumulation of activated intracellular trypsin | [140] | |
Autoimmune disorders | |||
Systemic lupus erythematosus | Enhanced autophagy in T cells | Enhanced autophagy causes imbalanced T cell subsets | |
Defect LC3-associated phagocytosis | Defect LC3-associated phagocytosis leads to blunted clearance of dying cells and elevated inflammation | [149] | |
Defect lysosomal acidification | Macrophages in lupus shows elevated lysosomal pH | [343] | |
Crohn’s disease | Defect autophagy | Human or mice deficient in ATG16L1 are more susceptible to Crohn’s disease | |
Defect lysosomal acidification | Elevated luminal pH links lysosomal dysfunction with Crohn’s disease risk | [344] | |
Rheumatoid arthritis | Impaired autophagy | Reduced autophagy links altered metabolism and T cell exhaustion | [152] |
Multiple sclerosis | Enhanced autophagy | Enhanced ATG5 expression in T cells is correlated with more sever disability | [153] |
Lysosomal storage disorder | |||
Niemann-Pick type C (NPC) disease | Npc1 or Npc2 mutation | Defective NPC1 or NPC2 causes lysosomal accumulation of cholesterol and glycosphingolipids leading to hepatic, pulmonary, and neuropsychiatric disorder | [345] |
Fabry disease | Galactosidase α mutation | Galactosidase α mutation causes globotriaosylceramide accumulation in lysosomes leading to vascular diseases | [346] |
Tay-Sachs disease | β-hexosaminidase α mutation | Deficient β-hexosaminidase α causes GM2 ganglioside accumulation in lysosomes of nerve cells leading to neuro disorder | [347] |
Mucopolysaccharidoses diseases | Mutation in mucopolysaccharide catabolic enzymes | Lysosomal accumulation of mucopolysaccharides leads to disorders in bone, cartilage, connective tissues, and nervous | [348] |
Pompe disease | α glucosidase mutation | Mutated α glucosidase causes glycogen accumulation in lysosomes leading to cardiac and respiratory failure | [349] |
Gaucher disease | glucosylceramidase β mutation | Glucosylceramide accumulates in macrophage lysosomes leading to disorder in visceral organs and nervous system | [162] |
