PINOCYTOSES Meaning and
Definition
-
Pinocytosis is a cellular process in which cells take in extracellular fluids, including dissolved solutes and molecules, by forming small vesicles through invagination of their plasma membrane. These small vesicles, known as pinocytic vesicles or pinosomes, are formed by the inward budding of the membrane to create a spherical, membrane-enclosed structure within the cell.
Pinocytosis is a non-specific and continuous process that occurs in various cell types throughout the body. It is important for the uptake of essential nutrients, such as proteins and vitamins, as well as the removal of waste materials, toxins, and pathogens from the extracellular environment.
This cellular mechanism can be categorized into two main types: constitutive pinocytosis and receptor-mediated pinocytosis. Constitutive pinocytosis refers to the continuous uptake of fluid and solutes by cells in a non-discriminatory manner. On the other hand, receptor-mediated pinocytosis is a more selective process that relies on specific receptors on the cell surface to recognize and bind to particular molecules before they are engulfed into the cell.
Pinocytosis plays a crucial role in a variety of physiological and pathological processes, including nutrient absorption, hormone regulation, immune responses, and the internalization of pathogens. Dysregulation of pinocytosis can lead to various disorders, such as lysosomal storage diseases and the abnormal accumulation of substances within cells.
In summary, pinocytosis is a cellular process by which cells internalize extracellular fluids and particles by forming small vesicles through invagination of their plasma membrane. It is involved in the uptake of nutrients, elimination of waste, and many other important functions within the cell.

Etymology of PINOCYTOSES
The term "pinocytosis" is derived from the Greek words "píno" (πίνω), meaning "I drink", and "kytos" (κύτος), meaning "cell". The suffix "-osis" is added to indicate that it refers to a cellular process or condition. Therefore, "pinocytosis" literally means "cell drinking" or "cellular ingestion", which reflects the process by which cells take in fluids and dissolved particles by forming vesicles from their plasma membrane.
