Human CD184/CXCR4 HEK293T Stable Cell Line

Introduction

The Human CD184/CXCR4 HEK293T Stable Cell Line is a powerful tool for studying the structure, activity, and application of the human chemokine receptor CXCR4. This stable cell line is derived from human embryonic kidney cells (HEK293T) and expresses the CD184/CXCR4 gene, which encodes for the CXCR4 protein. This cell line is widely used in research and drug development as CXCR4 is a key therapeutic target in various diseases, including cancer, HIV, and autoimmune disorders.

Structure of CXCR4

CXCR4 is a G protein-coupled receptor (GPCR) that is composed of 352 amino acids and has seven transmembrane domains. It is primarily expressed on the surface of immune cells, such as T cells, B cells, and monocytes, and plays a crucial role in cell migration, proliferation, and survival. The CXCR4 protein has a highly conserved structure, with a ligand-binding extracellular N-terminus and an intracellular C-terminus that interacts with G proteins to initiate downstream signaling pathways.

Activity of CXCR4

The activity of CXCR4 is regulated by its ligand, stromal cell-derived factor 1 (SDF-1 or CXCL12), which binds to the receptor and triggers a series of intracellular signaling events. This activation leads to the recruitment of G proteins, such as Gαi and Gβγ, which in turn activate downstream pathways, including the PI3K/Akt, MAPK, and NF-κB pathways. These signaling pathways are involved in various cellular processes, such as chemotaxis, cell survival, and proliferation.

Application of Human CD184/CXCR4 HEK293T Stable Cell Line

The Human CD184/CXCR4 HEK293T Stable Cell Line is a valuable tool for studying the role of CXCR4 in various diseases and for identifying potential therapeutic agents that target this receptor. One of the main applications of this cell line is in drug discovery and development. By using flow cytometry, researchers can screen potential drug candidates for their ability to bind to CXCR4 and modulate its activity. This can aid in the development of new treatments for diseases where CXCR4 plays a crucial role, such as cancer and HIV.

In addition, this stable cell line can also be used to study the mechanisms of CXCR4-mediated cell migration and proliferation. By manipulating the expression of CXCR4 in these cells, researchers can investigate the downstream signaling pathways and identify potential targets for therapeutic intervention.

Furthermore, the Human CD184/CXCR4 HEK293T Stable Cell Line can be used in studies on immune cell function. As CXCR4 is primarily expressed on immune cells, this cell line can be used to investigate the role of CXCR4 in immune cell migration and activation. This can provide insights into the pathogenesis of autoimmune disorders and aid in the development of new immunotherapies.

Conclusion

In summary, the Human CD184/CXCR4 HEK293T Stable Cell Line is a valuable tool for studying the structure, activity, and application of CXCR4. Its stable expression of CXCR4 allows for the investigation of its role in various diseases and the screening of potential therapeutic agents. With its wide range of applications, this cell line is an essential resource for researchers in the field of GPCR biology and drug development.
