Insights

Calcium signalling, crucial for cellular functions, involves tightly regulated calcium ion (Ca2+) dynamics. Dysfunctional Ca2+ signalling can lead to cell death pathways like necrosis or apoptosis.

Area of Science:

  • Cell Biology
  • Biochemistry
  • Physiology

Background:

  • Calcium signalling is a fundamental cellular process.
  • It regulates numerous cellular reactions through calcium-dependent enzymes.
  • Proper temporal and spatial control of calcium ions (Ca2+) is essential.

Purpose of the Study:

  • To elucidate the mechanisms of calcium signal generation and regulation.
  • To understand the role of calcium signalling in cellular responses.
  • To explore the link between pathological calcium signalling and cell death.

Main Methods:

  • Investigated the coordinated activity of calcium channels and transporters.
  • Analyzed the distribution of these proteins within intracellular compartments.
  • Examined the consequences of environmental insults and pathway overstimulation on calcium dynamics.

Main Results:

  • Calcium signals are generated by the coordinated action of various calcium channels and transporters.
  • These proteins are differentially distributed across intracellular compartments.
  • Pathological calcium signals, resulting from insults or overstimulation, can induce necrotic or apoptotic cell death.

Conclusions:

  • The calcium signalling system is central to cellular control.
  • Aberrant calcium signalling represents a critical mechanism in cell damage and death.
  • Understanding calcium dynamics is key to addressing cellular pathologies.

Cellular Injury IV: Necrosis01:16

Cellular Injury IV: Necrosis

Necrosis is a form of irreversible cell death caused by severe injury such as ischemia, toxins, or trauma. Unlike programmed cell death, it is an uncontrolled, pathological process that typically provokes inflammation in surrounding tissues.Pathophysiologic ChangesNecrosis begins when cells sustain critical damage, leading to swelling of organelles, particularly mitochondria, and rapid ATP depletion. As energy levels decline, membrane ion pumps fail, leading to calcium influx and eventually,...
Overview of Cell Death01:30

Overview of Cell Death

Cell death is an essential process where the body gets rid of old or damaged cells. Cell proliferation and death need to be balanced, as an imbalance between the two may lead to cancer or autoimmune diseases.
Cell death was observed in the early 19th century, but there was no experimental evidence to prove it. In 1842, Carl Vogt first discovered cell death in a metamorphic toad; however, it was not termed ‘cell death.’ Scientists discovered different cell death pathways only in the 20th century...
Skeleton and Calcium Homeostasis01:21

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.
Cellular Injury IlI: Cellular Death01:11

Cellular Injury IlI: Cellular Death

Cell death is the irreversible loss of cellular structure and function, representing the final stage of severe injury. It plays a key role in both normal physiology and disease.Types of Cell DeathThe two main types are necrosis and apoptosis, though others like necroptosis and pyroptosis also exist.Necrosis:Necrosis is an unregulated form of cell death caused by severe injury such as trauma, toxins, or ischemia. It is characterized by cell swelling, membrane loss, rupture, and leakage of...
Feedback Regulation of Calcium Concentration01:27

Feedback Regulation of Calcium Concentration

Calcium is an essential signaling molecule required for various cellular functions. Calcium pumps and ion channels on cell and organellar membranes, such as those on the endoplasmic reticulum (ER), regulate calcium concentrations inside the cell. They remain closed, keeping the cytosolic calcium levels low at a resting state.
Various transmembrane receptors, such as G protein-coupled receptors (GPCRs), elicit a response to extracellular signals by increasing cytosolic calcium. Activated GPCRs...
Necrosis01:16

Necrosis

Necrosis is considered as an “accidental” or unexpected form of cell death that ends in cell lysis. The first noticeable mention of “necrosis” was in 1859 when Rudolf Virchow used this term to describe advanced tissue breakdown in his compilation titled “Cell Pathology”.
Morphological Manifestations of Necrosis
Necrotic cells show different types of morphological appearance depending on the type of tissue and infection. In coagulative necrosis, cells become anucleated and die, but their...
