The Parathyroid Glands

The Parathyroid Glands

The two pairs of parathyroid glands embedded within the posterior surface of the thyroid gland are restricted by a dense capsule around them. These glands comprise two distinct cell populations—parathyroid oxyphil and parathyroid principal cells- pivotal in calcium homeostasis.
Oxyphil cells, whose functions remain elusive, emerge during late puberty, adding a layer of complexity to the parathyroid gland's intricacies. In contrast, principal parathyroid cells undertake a vital role by producing...

Hormones and Bone Tissue

Hormones and Bone Tissue

The endocrine system produces and secretes hormones, which interact with the skeletal system. These hormones control bone growth, maintain bone once it is formed, and remodel it.
Hormones That Influence Osteoblasts and/or Maintain the Matrix
Several hormones are necessary for controlling bone growth and maintaining the bone matrix. The pituitary gland secretes growth hormone (GH), which, as its name implies, controls bone growth. This happens in several ways: first, it triggers chondrocyte...

Synthesis and Functions of Calcitonin

Synthesis and Functions of Calcitonin

Calcitonin, a vital polypeptide hormone, regulates calcium levels within body fluids. It is released by the parafollicular cells, also known as C cells, situated in the follicular epithelium of the thyroid gland. Calcitonin responds to fluctuations in blood calcium levels and the influence of gastrointestinal hormones like gastrin and cholecystokinin.
The exact mechanisms by which calcitonin operates in calcium homeostasis remain elusive, but its significance is evident in several vital...

Skeleton and Calcium Homeostasis

Skeleton and Calcium Homeostasis

Calcium is not only the most abundant mineral in bone but also the most abundant mineral in the human body. Calcium ions are needed for bone mineralization, tooth health, heart rate regulation and strength of contraction, blood coagulation, the contraction of smooth and skeletal muscle cells, and the regulation of nerve impulse conduction. The average calcium level in the blood is about 10 mg/dL. When the body cannot maintain this level, a person will experience hypo or hypercalcemia.

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...

Hyperthyroidism II: Pathophysiology

Hyperthyroidism II: Pathophysiology

Hyperthyroidism is a hypermetabolic state caused by elevated levels of thyroid hormones, triiodothyronine (T3) and thyroxine (T4). It results from dysregulation at the thyroid, pituitary, or immune system level and affects multiple organ systems.PathophysiologyThe most common cause of hyperthyroidism is Graves’ disease, an autoimmune disorder in which antibodies, specifically thyroid-stimulating antibodies (TSAb), a subtype of TSH receptor antibodies (TRAb), bind to and activate TSH receptors...

Summary

Parathyroid hormone (PTH) may influence the immune system, but research is inconsistent. Further studies are needed to clarify if PTH has immunomodulatory effects in osteoporosis management.

Area of Science:

Immunology
Endocrinology
Pharmacology

Background:

Parathyroid hormone (PTH) and its analogue teriparatide are used in osteoporosis management.
PTH receptors are present on various immune cells, including neutrophils, B cells, and T cells.
Previous in vitro studies suggest a potential immunomodulatory role for PTH.

Purpose of the Study:

To review and synthesize the existing evidence on the immunomodulatory effects of parathyroid hormone (PTH).
To address the inconsistencies in previous research regarding PTH's role in immune function.

Main Methods:

Analysis of in vitro studies evaluating PTH's effects on immune cells.
Consideration of methodological variations, including PTH formulations, dosages, and incubation periods.
Examination of studies involving uremic patients and the impact of uremic toxins.

Main Results:

In vitro studies on PTH's immunomodulatory effects have yielded inconsistent results.
Methodological heterogeneity, including different PTH sources and experimental conditions, complicates interpretation.
The influence of uremic toxins in some studies further complicates the understanding of PTH's direct effects.

Conclusions:

The precise immunomodulatory role of PTH remains unclear due to inconsistent research findings.
Parathyroidectomy has been observed to reverse immune defects in individuals with high PTH levels, but clinical significance is uncertain.
Additional well-controlled studies are required to definitively establish whether PTH exerts immunomodulatory effects.
