The role of lysosomes in overall intracellular protein degradation depends on the cell type and nutritional conditions. Lysosomes are responsible for most protein degradation in liver and kidney, and certain lysosomal pathways of proteolysis are activated in response to nutritional deprivation. On the ...
Secretory lysosomes, also known as lytic granules, contain proapoptotic granzymes and perforin and can also participate in the regulation of immune cell functions. Natural killer (NK) cells and cytotoxic T lymphocytes (CTLs) play a crucial role in immunity, as they are responsible for the elimin...
Lysosomes are responsible for breaking down and recycling intracellular materials (through autophagy) and extracellular materials (through endocytosis and phagocytosis), which are then used to generate new cellular components and nutrients to meet the needs of cell metabolism and growth (Fig.2).2,5,35...
Lysosomes are enriched in hydrolytic enzymes working low pH that include proteases, lipases, glycosidases, nucleases, phosphatases, and sulfatases, and are responsible for elimination of “unwanted” molecules derived from both the cell itself (autophagy, cf. Fig. 62) or from outside of the cells...
On the one hand, lysosomes degrade CTLA-4; on the other hand, lysosomes are responsible for CTLA-4 transport to the plasma membrane. CTLA-4 can bind to activator protein 1 (AP1) and AP2 [113, 114] to promote its transport to lysosomes for degradation. In addition, CTLA-4 can enter ...
Changes in the lysosomes of senescent tissues and organisms are common and have been used as biomarkers of aging. Lysosomes are responsible for the degradation of many macromolecules, including proteins. At least five different pathways for the delivery of substrate proteins to lysosomes are known. ...
Lysosomes are single membrane-bound organelles characterized by an acidified milieu (pH: 4.5–5.5) and responsible for the degradation of biological macromolecules and maintenance of cellular homeostasis1,2,3,4,5. Lysosomes are essential for different types of autophagy, including nonspecific macroautopha...
Lysosomes are membrane-bounded organelles predominantly found animal cells. Explore the definition, structure, function & diagram of lysosomes only @ BYJU'S.

Lysosomes are membrane-bound, dense granular structures containing hydrolytic enzymes responsible mainly for intracellular and extracellular digestion.
