Lysosomes are vesicles that contain digestive enzymes. They are only present in animal cells. They function as part of the cell’s recycling system and can also help initiate cell death.

University of Virginia scientists discover new cell organelle called "hemifusome" that helps manage cellular recycling.

The proton levels or pH inside the autophagic vesicles change from 6–6.5 to 4.5 as we go from autophagosomes to autolysosomes ...

This "transmembrane" region is known to house a channel that helps membranous vesicles, such as lysosomes, regulate pH—a measure of acidity or alkalinity—by transporting pH-lowering protons ...

Lysosomes are basically the cell’s trash and recycling centers. ... That’s called a vesicle, or more precisely, a phagosome. Then the phagosome fuses with a lysosome to form a phagolysosome.

The proton levels or pH inside the autophagic vesicles changes from 6-6.5 to 4.5 as we go from autophagosomes to autolysosomes to lysosomes. Therefore, pH serves as an indicator for identifying ...

The lysosome was once thought of as the ... But a growing body of research shows that this enzyme-filled vesicle is more active than it originally appeared to be—with some scientists now ...

The outer membrane of the sequestering vesicle breaks to become continuous with the membrane of the lysosome/vacuole. This membrane is then removed through a microautophagic process.

In cells, structures called lysosomes act as recycling centers that can digest different kinds of molecular material. Using microscopes at the SickKids Imaging Facility, Akriti Prashar, PhD, a ...

The scientists think proteins from this “secretome” could be fluid biomarkers for lysosome dysfunction (see Dec 2020 news). “These data suggest enhanced secretion of not only lysosomes but also ...
