Insights

Cancer cells exploit the endolysosomal system (ES). This review explores how two-pore channels (TPCs) and transient receptor potential mucolipins (TRPMLs) in the ES impact cancer immunity, highlighting research gaps.

Area of Science:

  • Cell Biology
  • Cancer Research
  • Immunology

Background:

  • Cancer cells disrupt the endolysosomal system (ES) to support hallmark capabilities.
  • Endolysosomal integrity relies on soluble hydrolases and membrane proteins, including TPCs and TRPMLs.
  • TPCs and TRPMLs are crucial for ES function and show therapeutic potential against cancer hallmarks.

Purpose of the Study:

  • To review the known roles of TPCs and TRPMLs in immunity.
  • To investigate the potential involvement of TPCs and TRPMLs in cancer immune evasion.
  • To identify research gaps concerning endolysosomal ion channels and cancer immunity.

Main Methods:

  • Literature review and synthesis of existing research.
  • Analysis of studies on TPCs and TRPMLs in cancer.
  • Exploration of the intersection between ES function and immune regulation.

Main Results:

  • TPCs and TRPMLs regulate key cancer hallmarks like proliferation and migration.
  • Endosomes and lysosomes are vital for immune processes including antigen presentation.
  • The role of TPCs and TRPMLs in cancer immunity remains largely unexplored.

Conclusions:

  • Understanding TPCs and TRPMLs in cancer immunity is critical for developing new therapies.
  • Further research is needed to elucidate how these ion channels influence cancer's interaction with the immune system.
  • Targeting endolysosomal ion channels may offer novel strategies to overcome cancer immune evasion.

Receptor Downregulation in MVBs01:15

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that  lead to cell proliferation, migration, and differentiation. Overexpression of EGFR  stimulates cells to proliferate. Excessive  EGFR...

Cancer Cell Migration through Invadopodia01:35

Cancer Cell Migration through Invadopodia

Invadosome is a broad category of cell surface structures with proteolytic activity that  degrades the extracellular matrix (ECM). Invadosomes are present in normal cell types, including macrophages, endothelial cells, and neurons, as well as tumor cells. Although the macrophage podosomes and tumor cell invadopodia are classified as invadosomes, they have different structures, molecular pathways, and functions. Podosomes are short structures that last for a few minutes. However,...

Intralumenal Vesicles and Multivesicular Bodies01:38

Intralumenal Vesicles and Multivesicular Bodies

Intraluminal vesicles (ILVs) are small vesicles 50-80 nm in diameter formed during the maturation of early endosomes. A specialized endosome containing numerous ILVs is called a multivesicular body (MVB). ILVs contain internalized molecules such as antigens, nucleic acids, proteins, and metabolites. Some of these molecules are released from the MVBs inside exosomes and are transported to other cells. Other MVBs contain molecules that are retained in the ILVs and are later degraded within the...

Cytotoxic T Cells-mediated Immune Response01:27

Cytotoxic T Cells-mediated Immune Response

Cytotoxic T cells are a vital component of the immune system. They have the remarkable ability to identify and target antigens on infected or abnormal cells. These antigens often originate from intracellular pathogens such as viruses or abnormal proteins cancer cells produce.
Immunological surveillance is the ability of immune cells to monitor and eliminate infected cells with intracellular pathogens, neoplastically transformed cells, and cells with non-self antigens. Cytotoxic T cells and NK...

lncRNA - Long Non-coding RNAs

In humans, more than 80% of the genome gets transcribed. However, only around 2% of the genome codes for proteins. The remaining part produces non-coding RNAs which includes ribosomal RNAs, transfer RNAs, telomerase RNAs, and regulatory RNAs, among other types. A large number of regulatory non-coding RNAs have been classified into two groups depending upon their length – small non-coding RNAs, such as microRNA, which are less than 200 nucleotides in length, and long non-coding RNA...

Selectins

Cell adhesion is  an essential aspect of multicellularity. While stable cell interactions usually occur between cells of the same type, transient cell interactions occur between cells of different tissue types, such as between neutrophils and endothelial cells. Selectins are one class of cell adhesion molecules (CAMs) that bind carbohydrate ligands to form transient cell adhesion. They are rod-like proteins with a long extracellular part of variable length ending with the lectin domain,...
