The influence of interferon-γ on cardiac and renal histopathological changes induced by carbamazepine

Abstract

Insights

Interferon-gamma (IFN-γ) mitigated fetal heart and kidney abnormalities caused by carbamazepine (CBZ) exposure in mice. This finding suggests IFN-γ may protect against CBZ-induced developmental toxicity.

Area of Science:

  • Developmental toxicology
  • Immunology
  • Pharmacology

Background:

  • Carbamazepine (CBZ) is a widely used antiepileptic drug.
  • CBZ exposure during pregnancy can lead to adverse fetal outcomes.
  • Investigating protective agents against drug-induced teratogenicity is crucial.

Purpose of the Study:

  • To evaluate the protective effect of Interferon-gamma (IFN-γ) against carbamazepine (CBZ)-induced fetal histopathological changes.
  • To assess the impact of IFN-γ on fetal growth parameters in the context of CBZ exposure.

Main Methods:

  • Pregnant mice were administered CBZ (240 mg/kg) or a combination of CBZ and IFN-γ.
  • Control groups received either distilled water or IFN-γ alone.
  • Fetal tissues (heart, kidney) were examined for histopathological alterations on day 18 of gestation.

Main Results:

  • CBZ treatment significantly reduced fetal weight, crown-rump length, and organ volumes compared to controls.
  • IFN-γ administration, alone or with CBZ, did not cause adverse effects.
  • IFN-γ significantly prevented CBZ-induced histopathological damage in fetal heart and kidney.

Conclusions:

  • Carbamazepine induces significant structural damage to fetal heart and kidney tissues.
  • Interferon-gamma demonstrates a protective role, reducing the teratogenic effects of carbamazepine.
  • IFN-γ holds potential as a therapeutic agent to mitigate CBZ-induced developmental toxicity.

Factors Affecting Renal Clearance: Renal Impairment

Renal dysfunction significantly impairs the renal clearance of drugs, leading to potential complications in drug therapy. Renal failure, which can be caused by various factors, poses a significant challenge in the elimination of drugs from the body.
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...

Renal Corpuscle

The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...

Renal Clearance01:23

Renal Clearance

The glomerular filtration rate (GFR) is a critical marker of kidney function, reflecting the efficiency of filtration by the glomeruli. Renal clearance of specific substances, such as inulin or creatinine, is commonly used to measure GFR.
Renal clearance refers to the volume of plasma cleared of a specific substance, such as creatinine, per unit of time. To measure clearance, urine samples are collected over a 24-hour period during each bladder voiding, followed by a single blood sample at the...

Renal Drug Clearance: Comparison Between Renal Excretion Methods

Renal clearance is a critical parameter encompassing kidney filtration, secretion, and reabsorption processes. It is calculated using a specific equation to determine the rate at which the kidneys clear a drug.
Renal clearance is often associated with the renal glomerular filtration rate (GFR), which represents the rate at which plasma is filtered through the glomeruli in the kidney. When drug reabsorption is minimal and there is no active secretion, renal clearance is closely related to the...

The Influence of Affect on Cognition

Positive affect significantly influences cognitive processes, including evaluation, memory, creativity, and social judgments. Compared to negative affect, positive emotional states promote more favorable interpretations of stimuli, cognitive flexibility, and heuristic processing. These effects highlight emotions' powerful role in shaping how individuals perceive, remember, and interact with the world.Influence on Evaluation and AttributionWhen individuals experience positive affect, they are...

The Influence of Cognition on Affect

Cognition plays a pivotal role in shaping emotional experiences, as demonstrated by Schachter and Singer’s two-factor theory of emotion. According to this model, emotion arises from a combination of physiological arousal and cognitive interpretation. The body’s physiological response to stimuli is ambiguous and only gains emotional significance through cognitive labeling. For instance, an increased heart rate and adrenaline surge while standing near an attractive person may be...
