Enzyme-linked Receptors

Enzyme-linked Receptors

Enzyme-linked receptors are proteins that act as both receptor and enzyme, activating multiple intracellular signals. This is a large group of receptors that include the receptor tyrosine kinase (RTK) family. Many growth factors and hormones bind to and activate the RTKs.
Neurotrophin (NT) receptors are a family of RTKs, including trkA, trkB, and trkC (tropomyosin-related kinase) receptors. TrkA is specific for nerve growth factor (NGF), neurotrophin-6, and neurotrophin-7. TrkB binds...

Receptor-mediated Endocytosis

Receptor-mediated endocytosis is when bulk amounts of specific molecules are imported into a cell after binding to cell surface receptors. The molecules bound to these receptors are taken into the cell through inward folding of the cell surface membrane, which is eventually pinched off into a vesicle within the cell. Structural proteins, such as clathrin, coat the budding vesicle.

One well-characterized example of receptor-mediated endocytosis is the...

Receptor Downregulation in MVBs

Receptor Downregulation in MVBs

Multivesicular bodies (MVBs) are mature endosomes that sort ubiquitinated proteins and then fuse with lysosomes to degrade the sorted proteins. Epidermal growth factor (EGF) and its receptor (EGFR) form a complex that can be internalized through endocytosis, sorted into an MVB, and later degraded.
The EGFR can initiate signaling pathways that lead to cell proliferation, migration, and differentiation. Overexpression of EGFR stimulates cells to proliferate. Excessive EGFR...

Background:

Sensory neurons extend dendritic processes to the skin to detect environmental stimuli.
The molecular mechanisms guiding sensory neuron dendritic outgrowth to the skin remain largely unknown.

Purpose of the Study:

To identify novel molecules that mediate the interaction between sensory neurons and the epidermis.
To elucidate the guidance cues directing dendritic branching towards the skin surface.

Main Methods:

Utilized genetic screening and live imaging techniques in model organisms.
Investigated molecular signaling pathways involved in neuronal development and epidermal interactions.

Main Results:

Identified a specific diffusible cue secreted by epidermal cells.
Demonstrated that this cue is essential for directing sensory neuron dendritic outgrowth to the skin.
Showcased the role of this molecule in mediating neuron-epidermis interactions.

Conclusions:

A novel diffusible cue plays a critical role in guiding sensory neuron dendrites to the skin.
This discovery provides new insights into the molecular basis of neuro-cutaneous interactions.
Potential implications for understanding and treating sensory neuropathies.
