Eksosyytti

Eksosyytti is a term originating from Greek, meaning "outside the cell." It refers to substances, structures, or processes that are located or occur on the exterior of a cell. This can encompass a wide range of biological entities and phenomena.

In cellular biology, the cell membrane is the primary boundary defining the exterior of a cell. Structures embedded within or attached to the outer surface of this membrane are considered exosotic. These can include glycoproteins, glycolipids, and receptors that play crucial roles in cell-cell communication, adhesion, and recognition. The extracellular matrix, a network of molecules outside animal cells, also represents an exosotic environment.

The term can also be used in a broader sense to describe anything external to a cellular organism, such as environmental factors or interactions with other organisms. For instance, a virus, while interacting with a host cell, can be considered exosotic to the host cell before it enters. In plant biology, the cuticle, a waxy layer on the epidermis, is an exosotic protective covering. The concept of exosocytti is fundamental to understanding cellular interactions and the relationship between cells and their surroundings.
