Autocrine :-
Autocrine signaling is a type of cell signaling in which a cell secretes a signaling molecule that binds to receptors on the same cell or neighboring cells of the same type, resulting in a response within that same cell. In other words, the signaling molecule acts as both the signal and the target cell for the signal. This type of signaling is important in processes such as cell growth, differentiation, and immune response.
Juxtacrine :-
Juxtacrine signaling, on the other hand, is a type of cell signaling in which a cell directly contacts and communicates with an adjacent cell by surface-to-surface contact, without the need for a secreted signaling molecule. This type of signaling involves the binding of proteins or other molecules on the surface of one cell to receptors on the surface of another cell, resulting in a response in the target cell. Juxtacrine signaling is important in processes such as cell adhesion, cell migration, and embryonic development.
