Summary
Melatonin receptors MT1 and MT2, crucial for melatonin
Area of Science:
- Biochemistry and molecular biology
- Neuroendocrinology
- Pharmacology
Background:
- Melatonin, a tryptophan derivative, regulates numerous physiological functions.
- Age-related decline in melatonin is linked to various disorders.
- Melatonin MT1 and MT2 receptors are key targets mediating melatonin's effects.
Observation:
- The discovery of melatonin receptors has been a long process since 1959.
- Melatonin receptors belong to the G protein-coupled receptor superfamily.
- Recent publications in Nature reveal the first crystal structures of human MT1 and MT2 receptors in inactive states.
Findings:
- The crystal structures of human MT1 and MT2 receptors have been determined.
- These structures represent the receptors in their inactive conformations.
- The findings provide unprecedented atomic-level detail of these G protein-coupled receptors.
Implications:
- Structural insights will advance understanding of melatonin receptor function.
- These findings pave the way for rational drug design targeting melatonin pathways.
- Future research can explore ligand binding and receptor activation mechanisms.

01:03Olfactory Receptors: Location and Structure
11.2K
The process of olfaction, also known as the sense of smell, is a sophisticated chemical response system. The specialized sensory neurons that facilitate this process, known as olfactory receptor neurons, are situated in an upper segment of the nasal cavity, known as the olfactory epithelium. Olfactory sensory neurons are bipolar, with their dendrites extending from the epithelium's apex into the mucus that lines the nasal cavity. Airborne molecules, when inhaled, traverse the olfactory...

02:13Types of Hormones
83.1K
Hormones can be classified into three main types based on their chemical structures: steroids, peptides, and amines. Their actions are mediated by the specific receptors they bind to on target cells.

01:31Internal Receptors
74.3K
Many cellular signals are hydrophilic and therefore cannot pass through the plasma membrane. However, small or hydrophobic signaling molecules can cross the hydrophobic core of the plasma membrane and bind to internal, or intracellular, receptors that reside within the cell. Many mammalian steroid hormones use this mechanism of cell signaling, as does nitric oxide (NO) gas.

Light plays a significant role in regulating the growth and development of plants. In addition to providing energy for photosynthesis, light provides other important cues to regulate a range of developmental and physiological responses in plants.

02:16Light Acquisition
9.4K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.
