Insuliinilaadsed

Insuliinilaadsed, also known as insulin-like substances, refer to a group of proteins and peptides that exhibit structural or functional similarities to insulin. These molecules play crucial roles in regulating glucose metabolism, cell growth, and differentiation. The most well-known members of this group are insulin and insulin-like growth factors (IGFs), which include IGF-1 and IGF-2.

Insulin is a hormone produced primarily by the beta cells of the pancreas and is essential for maintaining blood glucose levels within a narrow range. It facilitates cellular uptake of glucose, promotes glycogen synthesis in liver and muscle tissues, and influences lipid and protein metabolism.

Insulin-like growth factors are hormones with growth-promoting effects, primarily involved in childhood development and anabolic processes in adults. IGF-1, in particular, mediates many of the actions of growth hormone and is involved in cell proliferation, survival, and differentiation across various tissues.

Insuliinilaadsed also encompass other related peptides that may be expressed in different tissues or during specific developmental stages, often sharing structural motifs with insulin and IGFs. They may act through similar or distinct receptors, influencing diverse biological pathways.

Understanding insuliinilaadsed is significant for medical research, especially concerning metabolic disorders such as diabetes mellitus, where insulin production or action is impaired, and in oncology, where IGFs can influence tumor growth. Their study continues to advance knowledge of cellular communication, growth regulation, and metabolic control mechanisms.
