Neurulation01:30

Neurulation

47.3K
Neurulation is the embryological process which forms the precursors of the central nervous system and occurs after gastrulation has established the three primary cell layers of the embryo: ectoderm, mesoderm, and endoderm. In humans, the majority of this system is formed via primary neurulation, in which the central portion of the ectoderm—originally appearing as a flat sheet of cells—folds upwards and inwards, sealing off to form a hollow neural tube. As development proceeds, the...

The Retinoblastoma Gene

4.9K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...

Neural Regulation

Digestion begins with a cephalic phase that prepares the digestive system to receive food. When our brain processes visual or olfactory information about food, it triggers impulses in the cranial nerves innervating the salivary glands and stomach to prepare for food.

Nervous Tissue: Neuron Types

7.7K
Neurons, the fundamental units of the nervous system, can be classified based on both their structural and functional characteristics.
Structurally, neurons are categorized into three main types: multipolar, bipolar, and unipolar (or pseudounipolar). Multipolar neurons, which are the most common type in the brain and spinal cord, as well as all motor neurons, possess multiple dendrites and a single axon.
Bipolar neurons, on the other hand, have one primary dendrite and one axon. They are...

Enzyme-linked Receptors01:00

Enzyme-linked Receptors

88.9K
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...

Summary

Neurofibromatosis type 1 (NF1) is a common neurogenetic disorder affecting 1 in 2500 individuals. This review covers NF1

Area of Science:

  • Genetics and Molecular Biology
  • Neurology
  • Oncology

Background:

  • Neurofibromatosis type 1 (NF1), also known as von Recklinghausen disease, is a prevalent neurogenetic disorder.
  • NF1 affects approximately 1 in 2500 to 1 in 3500 individuals globally, irrespective of ethnicity.
  • It is distinct from neurofibromatosis type 2 (NF2).

Purpose of the Study:

  • To provide a comprehensive overview of the clinical and molecular characteristics of NF1.
  • To explore the molecular pathophysiology of NF1.
  • To identify novel therapeutic drug targets based on a deeper understanding of NF1.

Main Methods:

  • Literature review of clinical manifestations.
  • Analysis of molecular genetics and pathophysiology.

  • Discussion of emerging therapeutic strategies.

    • Main Results:

    • NF1 presents with diverse clinical features including café-au-lait macules, skinfold freckling, neurofibromas, brain tumors, iris hamartomas, and bony lesions.
    • Patients with NF1 have an elevated risk for learning disabilities, intellectual deficits, aqueductal stenosis, pheochromocytoma, vascular dysplasia, scoliosis, and various cancers.
    • Molecular insights into NF1 pathophysiology are paving the way for new drug development.

    Conclusions:

    • NF1 is a complex disorder with a wide spectrum of clinical presentations and associated risks.
    • Understanding the molecular basis of NF1 is crucial for developing effective treatments.
    • Targeted therapies based on molecular insights hold promise for improving patient outcomes in NF1.
