Positive and Negative Feedback Loops01:18

Positive and Negative Feedback Loops

19.9K
Animal organs and organ systems constantly adjust to internal and external changes through a process called homeostasis ("steady state"). Examples of these changes include regulation of the level of glucose or calcium in the blood or internal responses to external temperatures. Homeostasis requires  maintaining an internal dynamic equilibrium:

Multicompartment Models: Overview01:14

Multicompartment Models: Overview

223
Multicompartment models are mathematical constructs that depict how drugs are distributed and eliminated within the body. They segment the body into several compartments, symbolizing various physiological or anatomical areas connected through drug transfer processes such as absorption, metabolism, distribution, and elimination.
These models offer a more comprehensive representation of drug behavior in the body than one-compartment models. They accommodate the complexity of drug distribution,...

Pathophysiology of Heart Failure01:17

Pathophysiology of Heart Failure

1.8K
Heart failure (HF) is a progressive syndrome involving ventricles that leads to inadequate cardiac output. It can be classified based on location and output or ejection fraction. Ejection fraction (EF) is an essential measurement in the diagnosis and surveillance of HF. Reduced EF corresponds to systolic heart failure (HFrEF). However, HF with preserved ejection fraction (HFpEF) is becoming increasingly prevalent. Also known as diastolic HF, this form of HF is related to aging. The...

Homeostatic Imbalance01:10

Homeostatic Imbalance

24.8K
Homeostasis is the maintenance of a stable internal environment within the body, which is crucial for the proper functioning of cells, tissues, organs, and organ systems. The body has various control mechanisms that work together to regulate various physiological parameters such as temperature, blood pressure, pH balance, and fluid balance, to name a few. These control mechanisms are based on feedback loops that can be either positive or negative.
However, sometimes these feedback loops fail,...

Hypertension II: Pathophysiology01:29

Hypertension II: Pathophysiology

52
Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...

Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

6.4K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

Area of Science:

  • Systems biology
  • Theoretical biology
  • Disease mechanisms

Background:

  • Numerous diseases remain etiologically puzzling and difficult to treat.
  • Current approaches may overlook underlying uniform mechanisms in biological complexity.
  • Metabolic stability suggests reciprocal control is fundamental to life.

Purpose of the Study:

  • To propose a unifying hypothesis for disease etiology based on feedback loop mechanisms.
  • To reframe the understanding of biological systems and disease processes.
  • To identify potential critical therapeutic targets by analyzing feedback loops.

Main Methods:

  • Generalizing the role of feedback loops in all functional elements of biological systems.
  • Modeling life processes, including disease transitions, using positive and negative feedback loops.
  • Conceptual reduction of disease mechanisms to bistable or multistationary loop systems.

Main Results:

  • Hypothesizes that all functional biological elements operate within positive or negative feedback loops.
  • Suggests that disease initiation can be understood as a shift in these feedback loop systems.
  • Proposes a unifying model applicable to a wide range of diseases.

Conclusions:

  • A feedback loop-centric view offers a unified model for understanding disease.
  • This framework may lead to the identification of novel therapeutic strategies.
  • Further research into biological feedback systems is warranted for clinical applications.
