cyto-, cyt-, -cyte, cytio-

1. A branch of biology which deals with heredity and the cellular components; especially, chromosomes that are associated with heredity.
2. The study of the relationships between inheritance and the structure and function of cell components by using the sciences of cytology and genetics.

An intracellular deficiency of glucose.

1. Any protein secreted by lymph cells that affects cellular activity and controls inflammation.
2. Any of several regulatory proteins; such as, the interleukins and lymphokines, that are released by cells of the immune system and act as intercellular mediators in the generation of an immune response.
3. Any of a group of soluble proteins that are released by a cell to send messages which are delivered to the same cell (autocrine), an adjacent cell (paracrine), or a distant cell (endocrine).

The cytokine binds to a specific receptor and causes a change in function or in development (differentiation) of the target cell.

Cytokines are involved in reproduction, growth and development, normal homeostatic regulation, response to injury and repair, blood clotting, and host resistance (immunity and tolerance).

The process of division or segmentation of the cytoplasm (contents) of a cell, generally following a nuclear (central) division: "The cytokinesis of a cell is the separation into two daughter cells that doubles the chromosome number and results in the formation of two cells in living organisms, each of which has one set of chromosomes."

An occupation in the branch of biological science that deals with the structure, behavior, growth, and reproduction of cells and the function and chemistry of cells and cell components.
