Receptor fluid typically refers to the extracellular fluid that surrounds cells, providing a medium for the exchange of signaling molecules and nutrients. In the context of cellular signaling, it is essential for the binding of ligands to receptors on the cell surface, facilitating communication between cells and their environment. This fluid can play a critical role in processes such as hormone signaling, neurotransmission, and immune responses.

Receptor activation can happen within milliseconds to seconds when a ligand binds to the receptor, triggering a conformational change. The time it takes for the receptor to fully activate and initiate downstream signaling pathways can vary depending on the specific receptor and the cellular context.
Drugs that increase receptor activation are known as agonists. They bind to the receptor and produce a biological response. This can lead to a variety of effects depending on the specific receptor and drug involved.
A channel linked receptor transduces functions of the same protein molecule. An example of a channel linked receptor are neurotransmitters in the brain.

pinocytosis is a non-specific process where the cell engulfs extracellular fluid and particles, while receptor-mediated endocytosis is a selective process that relies on specific receptors binding to ligands for internalization. Receptor-mediated endocytosis is more efficient and targeted compared to pinocytosis.
Receptor-mediated endocytosis.It is the mechanism that allows cells to concentrate material that is present only in very small amounts into the extracellular fluid.
Important tissue receptor tumor markers include estrogen receptor (ER), progesterone receptor (PR), and human epidermal growth factor receptor 2 (HER2) in breast cancer; epidermal growth factor receptor (EGFR) and anaplastic lymphoma kinase (ALK) in lung cancer; and the androgen receptor (AR) in prostate cancer. These markers help guide treatment decisions and predict response to targeted therapies.
The glycoprotein CD4 is a co-receptor. A co-receptor is "a cell surface receptor, which, when bound to its respective ligand, modulates antigen receptor binding or affects cellular activation after antigen-receptor interactions." (MediLexicon)
