Pinealocyte

Pinealocytes are cells that are found in the pineal gland of the brain. They play an important role in regulating the circadian rhythm, that is, the sleep-wake cycle, which depends on the time of day.

Pinealocytes produce the hormone melatonin, which is responsible for regulating the circadian rhythm. Melatonin is released in the dark when the body is preparing for sleep, and reduces its activity during daylight hours.

In addition, pinealocytes are also involved in regulating other processes such as metabolism, the immune system, and mood.

However, despite their important role, pinealocytes can be susceptible to various diseases such as tumors, infections and other disorders.

Overall, studying pinealocytes and their role in regulating the circadian rhythm and other processes can help develop new treatments for various diseases and disorders.

Pinealoocytes are cells located in the central part of the pineal gland, which is a small, bean-shaped organ located in the area between the brain and pituitary gland at the base of the brain.

The pineal gland is not a parenchymal organ and makes up about 6% of the mass of the brain. The pineal gland secretes the hormone melatonin, which is responsible for regulating the sleep-wake cycle by synchronizing the body's activity rhythm with the day-night cycle. Thus, pinealoicite plays an important role in regulating the body's circadian rhythms.

When studying the structure of the pineal organ, it was possible to establish that the functions of its tissue cells do not fully correspond to the classical hormone-forming interpretation. According to the authors (Borges G. M., Wittenberg M. E.), pineal hormone is formed
