Hypothalamic-Pituitary Axis01:37

Hypothalamic-Pituitary Axis

70.3K
The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.

EPS and iPS Cells in Disease Research

3.5K
Embryonic and induced pluripotent stem cells are excellent models for disease research because of their ability to self-renew and differentiate into most cell types. Somatic cells from a patient are isolated and reprogrammed into induced pluripotent stem cells or iPSCs. These iPSCs are later differentiated into the desired cell type, which mirrors the diseased cell of the patient. In this way, disease models have been created for investigating diseases such as Down syndrome, type I diabetes,...

Adrenal Gland Disorders01:27

Adrenal Gland Disorders

3.9K
Adrenal gland disorders manifest when the production of adrenal hormones deviates from the norm, resulting in either excessive or insufficient concentrations.
Adrenal insufficiency, characterized by insufficient cortisol and aldosterone production, leads to conditions like Addison's disease. This disorder, affecting the adrenal cortex, exhibits symptoms such as skin bronzing, dehydration, low blood pressure, fatigue, and weight loss. Congenital adrenal hyperplasia, a genetic ailment causing...

Gastritis-II: Pathophysiology01:17

Gastritis-II: Pathophysiology

1.7K
Gastritis is marked by disruption of the mucosal barrier that usually protects the stomach tissue from digestive juices and manifests in acute and chronic forms.
In acute gastritis, the gastric mucosa becomes swollen and red and undergoes superficial erosion. Superficial ulceration may lead to bleeding.
In chronic gastritis, persistent or repeated insults lead to chronic inflammatory changes and, eventually, thinning or atrophy of the gastric tissue.
Gastritis can stem from various causes, each...

Area of Science:

  • Endocrinology
  • Immunology
  • Pathology

Background:

  • Hypophysitis is a rare inflammatory condition affecting the pituitary gland.
  • Clinical and radiological signs are often non-specific, complicating diagnosis.
  • The exact pathogenesis of hypophysitis remains largely unknown.

Purpose of the Study:

  • To review recent advancements in understanding hypophysitis.
  • To highlight newly identified etiological and histological variants.
  • To discuss the diagnostic challenges and potential autoantigens.

Main Methods:

  • Literature review of recent studies on hypophysitis.
  • Analysis of reported cases and histological findings.
  • Examination of emerging etiological factors and diagnostic criteria.

Main Results:

  • New variants of hypophysitis have been described, including immunoglobulin G4-related hypophysitis.
  • Hypophysitis associated with ANCA-associated vasculitis is reported for the first time.
  • Monoclonal antibodies targeting CTLA-4 can induce hypophysitis in cancer patients.

Conclusions:

  • Hypophysitis diagnosis remains challenging due to non-specific clinical and radiological features.
  • Recent discoveries include new histological subtypes and etiological links.
  • Despite identifying candidate pituitary autoantigens, effective diagnostic tools are still lacking.
