Summary
Protocadherins, a large group of cell adhesion molecules, are crucial for brain development. Emerging research highlights their roles beyond adhesion, including neuronal identity and function, particularly in the hypothalamus.
Area of Science:
- Neuroscience
- Developmental Biology
- Molecular Biology
Background:
- Cell-cell adhesion proteins, like cadherins, are vital for tissue development.
- Protocadherins are the largest cadherin subfamily, mediating cell adhesion in the developing brain.
- Their roles in neural development are increasingly recognized.
Purpose of the Study:
- To review the current understanding of protocadherin function in brain development.
- To explore the specific roles of protocadherins in the hypothalamus.
- To emphasize the significance of protocadherins in neural development and disorders.
Main Methods:
- Review of existing scientific literature on protocadherins.
- Analysis of expression profiles and genetic manipulation studies.
- Examination of protocadherin structure, genomics, and molecular functions.
Main Results:
- Protocadherins mediate homophilic cell-cell adhesion during neural development.
- They may function as molecular identity markers for neurons, guiding recognition and migration.
- Vast variations in protocadherin structure contribute to neuronal diversity.
Conclusions:
- Protocadherins play multifaceted roles in brain development, extending beyond simple adhesion.
- Further research is needed to fully elucidate their functions in the hypothalamus.
- Understanding protocadherins may offer insights into neuroendocrine disorders.

4.6K
The cadherins are a superfamily of cell adhesion molecules comprising over 180 variants, with specific tissues expressing a particular combination of cadherin types. Cadherins generally exhibit homophilic binding; i.e., cadherins on one cell bind to cadherins of the same or closely related type on another cell. Thus, cells of the same type have a specific affinity to bind to each other and sort themselves into clusters to form tissues.

01:25Structure of Cadherins
5.3K
The cadherins were one of the first cell adhesion molecules discovered; the term “cadherins” is based on their calcium-dependent adhering properties. The first cadherins discovered on the epithelial, neuronal, and placental cells were named E-cadherin, P-cadherin, and N-cadherin, respectively. These classical cadherins share sequence and structural similarities. Other cadherins, including those involved in cell signaling, are grouped into non-classical cadherins. This...

5.4K
The hypothalamus is a small yet highly complex and essential brain region that plays a crucial role in regulating various bodily functions. Anatomically, it is located at the base of the brain, just above the brainstem and below the thalamus, forming part of the limbic system.
The hypothalamus interacts with other brain regions, including the pituitary gland, through a direct physical connection called the hypothalamic-pituitary axis. The hypothalamus receives somatic and visceral inputs and...

During embryogenesis, cells become progressively committed to different fates through a two-step process: specification followed by determination. Specification is demonstrated by removing a segment of an early embryo, “neutrally” culturing the tissue in vitro—for example, in a petri dish with simple medium—and then observing the derivatives. If the cultured region gives rise to cell types that it would normally generate in the embryo, this means that it is specified. In...

The Hedgehog gene (Hh) was first discovered due to its control of the growth of disorganized, hair-like bristles phenotype in Drosophila, much like hedgehog spines. Hh plays a crucial role in the development of organs and the maintenance of homeostasis in both invertebrates and vertebrates. However, while Drosophila has only one Hh protein, mammals have multiple functional Hedgehog proteins - Sonic (Shh), Desert (Dhh), and Indian Hedgehog (Ihh). All of these homologous proteins have adapted to...

71.2K
The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.
