Major Hormones and Their Functions

Major Hormones and Their Functions

Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and...

Functions of Thyroid Hormones

Functions of Thyroid Hormones

The thyroid hormone (TH) plays a pivotal role in the intricate orchestration of physiological processes, exerting profound effects on development, metabolism, and homeostasis throughout different life stages.
TH is indispensable for the normal development and maturation of the skeletal, muscular, and nervous systems during fetal and childhood growth. It facilitates bone mineral turnover and regulates protein synthesis in developing tissues, contributing significantly to overall growth and...

Plant Hormones

Plant Hormones

Plant hormones—or phytohormones—are chemical molecules that modulate one or more physiological processes of a plant. In animals, hormones are often produced in specific glands and circulated via the circulatory system. However, plants lack hormone-producing glands.

Hormonal Regulation

Hormonal Regulation

The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

Hormonal Regulation

Hormonal Regulation

Hormones regulate a significant portion of digestion through activation of the neuroendocrine system. The neuroendocrine system of digestion contains many different hormones all with multiple functions that are both, directly and indirectly, involved in digestion.

Types of Hormones

Types of Hormones

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.

Regenerative Medicine

Background:

Cognitive impairment is a frequent consequence for stroke survivors.
Growth hormone (GH) shows potential for cognitive enhancement in various conditions.
This study investigates GH's therapeutic effects on post-stroke cognitive function.

Purpose of the Study:

To evaluate the impact of peripheral GH administration on cognitive function in a mouse model of stroke.
To explore the underlying mechanisms, including neurotrophic factor levels, neuroplasticity, and cerebrovascular remodeling.

Main Methods:

Experimental stroke induced via photothrombotic occlusion in mice.
Associative memory assessed using a paired-associate learning task on a touchscreen platform.
Neural tissue loss, neurotrophic factors (IGF-1, VEGF), and markers of neuroplasticity (SYN-1, MBP) and vascular remodeling (CD31, collagen-IV) were analyzed.

Main Results:

GH-treated mice showed significant improvement in the paired-associate learning task compared to controls.
GH treatment reduced neural tissue loss and increased levels of IGF-1 and VEGF in both circulation and peri-infarct areas.
GH promoted neuroplasticity markers (SYN-1, MBP) and enhanced vascularization (CD31, collagen-IV) in the peri-infarct region.

Conclusions:

GH administration demonstrates significant cognitive recovery benefits in a preclinical stroke model.
GH treatment positively influences key mechanisms of neuroplasticity and vascular repair post-stroke.
These findings support GH as a potential therapeutic agent for stroke recovery.
