Cell Signaling

Front

What is cell signaling?

Back

Cell signaling is the process by which cells communicate with each other to coordinate their activities, often involving signaling molecules and receptors.

Front

What is a ligand?

Back

A ligand is a signaling molecule that binds to a specific receptor on a target cell, initiating a cellular response.

Front

What happens after a cellular response is achieved?

Back

The ligand and receptor separate, terminating the signaling process.

Front

What is a stem cell?

Back

A stem cell is a precursor cell that can differentiate into various cell types in the body.

Front

What are surface receptor inhibitors?

Back

Surface receptor inhibitors are molecules that block the interaction between ligands and their receptors, interfering with cell signaling.

Front

What is gene expression?

Back

Gene expression is the process by which information from a gene is used to synthesize functional gene products, typically proteins.

Front

What is the role of growth factors in cell signaling?

Back

Growth factors are signaling molecules that stimulate cell growth, proliferation, and differentiation.

Front

What are myeloid blast cells?

Back

Myeloid blast cells are immature cells in the bone marrow that can develop into various types of blood cells, including red blood cells and platelets.

Front

What is leukemia?

Back

Leukemia is a type of cancer that affects blood cells, characterized by the overproduction of abnormal white blood cells.

Front

What is a second messenger?

Back

A second messenger is a molecule that relays signals received at receptors on the cell surface to target molecules inside the cell.
