The NLRP3 inflammasome is a multimeric protein complex that initiates an inflammatory
form of cell death and triggers the release of proinflammatory cytokines IL-1β and IL-18. The …

The endoplasmic reticulum (ER) is the largest organelle in the cell, and its functions have
been studied for decades. The past several years have provided novel insights into the …

The view of the lysosome as the terminal end of cellular catabolic pathways has been
challenged by recent studies showing a central role of this organelle in the control of cell …

Lysosomes are the main proteolytic compartments of mammalian cells comprising of a
battery of hydrolases. Lysosomes dispose and recycle extracellular or intracellular …

Since the discovery of lysosomes more than 70 years ago, much has been learned about
the functions of these organelles. Lysosomes were regarded as exclusively degradative …

In recent years, rapid discoveries have been made relating to Ca 2+ handling at specific
organelles that have important implications for whole-cell Ca 2+ homeostasis. In particular …

The ATP-dependent proton pump V-ATPase ensures low intralysosomal pH, which is
essential for lysosomal hydrolase activity. Based on studies with the V-ATPase inhibitor …

Summary Endocytic cargo and Rab GTPases are segregated to distinct domains of an
endosome. These domains maintain their identity until they undergo fission to traffic cargo. It …

Calcium (Ca 2+) is considered one of the most-important biological cations, because it is
implicated in cell physiopathology and cell fate through a finely tuned signaling system. In …

Abstract Macroautophagy (hereafter called 'autophagy') is a cellular process for degrading
and recycling cellular constituents, and for maintenance of cell function. Autophagy initiates …
