ICD or immunogenic apoptosis is a form of cell death resulting in a regulated activation of the immune response. This cell death is characterized by apoptotic morphology, [3] maintaining membrane integrity. Endoplasmic reticulum (ER) stress is generally recognised as a causative agent for ICD, with high production of reactive oxygen species ...
Osmotic fragility is affected by various factors, including membrane composition and integrity as well as the cells' sizes or surface-area-to-volume ratios. [ 3 ] [ 4 ] [ 5 ] The osmotic fragility test is common in hematology , and is often performed to aid with diagnosis of diseases associated with RBC membrane abnormalities.
>: The membrane is in the liquid-crystal phase, the membrane is less ordered and more fluid. At 37 °C, this is the state of the membrane: the presence of cholesterol, though, allows for the membrane stabilization and a more compact organization. The composition of a membrane can also affect its fluidity.
Assessing cell membrane integrity is one of the most common ways to measure cell viability and cytotoxic effects. Compounds that have cytotoxic effects often compromise cell membrane integrity. Vital dyes, such as trypan blue or propidium iodide are normally excluded from the inside of healthy cells; however, if the cell membrane has been ...
Toroidal model: The toroidal model proposes that AMPs interact with the lipid bilayer of the microbial cell membrane to form toroidal structures, which are thought to pinch off sections of the membrane and lead to the formation of vesicles. This process is thought to disrupt the membrane's integrity and cause the death of the microbe.
Staverman's reflection coefficient, σ, is a unitless constant that is specific to the permeability of a membrane to a given solute. [ 4 ] The Starling equation, written without σ , describes the flow of a solvent across a membrane that is impermeable to the solutes contained within the solution.
A cell membrane is simplified as lipid bilayer plus membrane skeleton. The skeleton is a cross-linking protein network and joints to the bilayer at some points. Assume that each proteins in the membrane skeleton have similar length which is much smaller than the whole size of the cell membrane, and that the membrane is locally 2-dimensional ...
Donnan equilibrium across a cell membrane (schematic). The Gibbs–Donnan effect (also known as the Donnan's effect, Donnan law, Donnan equilibrium, or Gibbs–Donnan equilibrium) is a name for the behaviour of charged particles near a semi-permeable membrane that sometimes fail to distribute evenly across the two sides of the membrane.
