The TRH controls the release of thyroid-stimulating hormone (TSH) from the pituitary. One of these processes is regulation of thyroid function.įor example, the dominant signal to the brain that suppresses the expression of TRH (thyrotropin-releasing hormone) in the paraventricular nucleus (PVN) of the hypothalamus is a decline in levels of the hormone leptin. Thanks to its role in body fat regulation, leptin takes part in a number of processes in a human body. Leptin’s impact on regulation of thyroid function That’s why this hormone is deeply connected to overweight/obesity and weight loss process. The more body fat adipocytes carry, the more leptin they produce. the amount of calories we eat and expend, and how much we store in our body. Leptin, also known as starvation or satiety hormone, targets hypothalamus to regulate long-term energy balance i.e. Īutocrine signaling refers to the production and secretion of an extracellular mediator by a cell followed by its binding to receptors on the same cell to kick-start the process of signal transduction. ![]() Paracrine signaling molecules are released from paracrine cells and they diffuse locally through the extracellular fluid, act as mediators by targeting cells nearby. To clarify, endocrine signaling is the most prevalent type of cell signaling and it revolves around sending a signal through the body by secreting hormones into the bloodstream. Leptin acts as both endocrine and paracrine factor, but it can function as an autocrine factor too. Through communication with the brain, leptin controls hunger and behavior and sends a signal to inform your body it’s full and it should stop eating.Įvidence shows this hormone has many other roles such as a “growth factor in various cell types”, a permissive factor for puberty, a signal of metabolic status, a modulation between fetus and maternal metabolism, and it interacts with other hormonal mediators and “regulators of energy status and metabolism such as ghrelin, insulin, the insulin-like growth factors” and others. The primary role of the hormone is to regulate body fat. Leptin is a hormone produced by adipocytes or fat cells in the body. In previous articles, we’ve discussed the impact of progesterone and estrogen on thyroid health, and this post will elucidate the role of leptin. Not only do hormones regulate our sexual and reproductive health, but everything else including hunger, food intake, body fat regulation, you name it. When a term hormone comes to mind we immediately think of estrogen, progesterone, and testosterone.Ī wide range of hormones are released into our body and all of them have unique functions that are necessary for good health and wellbeing. 5.1 Does thyroid influence leptin levels?.4 Thyroid autoimmunity and leptin resistance.2 Leptin’s impact on regulation of thyroid function. ![]()
