Somatosensation01:33

Somatosensation

36.9K
The somatosensory system relays sensory information from the skin, mucous membranes, limbs, and joints. Somatosensation is more familiarly known as the sense of touch. A typical somatosensory pathway includes three types of long neurons: primary, secondary, and tertiary. Primary neurons have cell bodies located near the spinal cord in groups of neurons called dorsal root ganglia. The sensory neurons of ganglia innervate designated areas of skin called dermatomes.

Receptor Downregulation in MVBs

2.0K
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...

Receptor Tyrosine Kinases01:26

Receptor Tyrosine Kinases

15.5K
Receptor tyrosine kinases or RTKs are membrane-bound receptors that phosphorylate specific tyrosine on protein substrates. RTKs regulate cellular growth, differentiation, survival, and migration. They contain an extracellular ligand binding domain, a transmembrane domain, and a cytosolic tail with intrinsic kinase activity. Several extracellular signaling molecules activate RTKs in one or more ways and relay the signal downstream. Ligands such as platelet-derived growth factor (PDGF) or...

Area of Science:

  • Endocrinology and Neuroscience
  • Molecular Imaging and Nuclear Medicine

Background:

  • Somatostatin is a peptide hormone with widespread inhibitory effects in the nervous system and endocrine organs.
  • Five somatostatin receptor subtypes are expressed in human tumors, with subtype 2 being highly prevalent on neuroendocrine tumor cells.

Purpose of the Study:

  • To review the development of single photon emission radiopharmaceuticals for studying somatostatin receptors.
  • To highlight the application of these radiopharmaceuticals in diagnostic imaging of tumors.

Main Methods:

  • Development and application of single photon emission radiopharmaceuticals.
  • Molecular imaging techniques targeting somatostatin receptors.

Main Results:

  • Somatostatin receptor overexpression on tumor cells compared to normal tissues is the basis for molecular imaging.
  • Single photon emission radiopharmaceuticals enable visualization of these overexpressed receptors.

Conclusions:

  • Single photon emission radiopharmaceuticals are valuable tools for the diagnostic imaging of somatostatin receptor-expressing tumors.
  • Targeting somatostatin receptors offers a molecular basis for improved tumor detection and characterization.
