GPI Anchoring of Proteins in the ER Membrane01:29

GPI Anchoring of Proteins in the ER Membrane

5.6K
GPI-anchoring is a post-translational, reversible protein modification that is ubiquitous in eukaryotes. Such proteins are primarily present on the exoplasmic leaflet of the plasma membrane.
GPI-anchor structure
A sequence of 11 enzymatic reactions results in the synthesis of the complete GPI anchor consisting of a hydrophobic and a hydrophilic portion. The hydrophobic portion comprises phosphatidylinositol, while the hydrophilic part comprises polar groups like phosphoethanolamine,...

Treating Helicobacter pylori in Peptic Ulcers: Antimicrobial Therapy

1.3K
Helicobacter pylori, a resilient gram-negative bacterium, can thrive in the stomach's harsh, acidic environment. Infection with H. pylori leads to a cascade of events within the stomach lining. One of the critical disruptions caused by this bacterium is the interference with somatostatin production, a hormone responsible for regulating acid secretion. This interference tips the balance, escalating acid secretion and diminishing bicarbonate levels. This imbalance compromises the defensive...

The Anchoring-and-Adjustment Heuristic

7.8K
In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...

Anchoring Junctions01:03

Anchoring Junctions

5.0K
Anchoring junctions are multiprotein complexes that help cells connect to other cells and the extracellular matrix. Anchoring junctions are present on the lateral and basal surfaces of cells, providing strong and flexible connections. Focal adhesions are often formed due to cell interactions with the ECM substrata, which initiate signal transduction via kinase cascades and other mechanisms. Together, they provide stability and tissue integrity. There are three types of anchoring junctions:...

Lipids as Anchors01:32

Lipids as Anchors

7.4K
In the plasma membrane, the lipids forming the bilayer can also act as an anchor to tether proteins to the membrane. The three main types of lipid anchors found in eukaryotes are – prenyl groups, fatty acyl groups, and glycosylphosphatidylinositol or GPI groups. Prenyl and fatty acyl groups act as anchors on the cytosolic surface of the membrane, whereas GPI anchors proteins on the extracellular side.
The carboxy-terminal of most of the prenylated proteins, such as Ras proteins, contains...

Complement System01:27

Complement System

10.8K
The complement system is a group of approximately 20 plasma proteins that strengthen the body's defenses against infections through opsonization, inflammation, and cell lysis. Opsonization involves coating pathogens with complement proteins, making them more recognizable and facilitating phagocyte engulfment. Certain complement proteins induce inflammation that attracts immune cells to the site of infection. Cell lysis involves the destruction of pathogens through the formation of a...

Area of Science:

  • Quantum Optics
  • Condensed Matter Physics
  • Materials Science

Background:

  • Controlling electron dynamics with light fields is crucial for ultrafast phenomena.
  • Strong-field light-matter interactions are well-studied in dielectrics but less so in conductors due to screening.
  • Graphene offers unique properties like broadband response and weak screening, making it ideal for studying light-field control in conductors.

Purpose of the Study:

  • To investigate light-field-driven electron dynamics in monolayer graphene.
  • To explore the control of electron currents using the electric-field waveform of laser pulses.
  • To understand the transition from weak-field to strong-field light-matter interaction regimes in graphene.

Main Methods:

  • Irradiation of monolayer graphene with two-cycle laser pulses.
  • Measurement of induced current sensitivity to the carrier-envelope phase (CEP) of laser pulses.
  • Analysis of current reversal as a function of driving field amplitude.

Main Results:

  • Attosecond-level sensitivity of induced current to the laser electric-field waveform (CEP).
  • Observation of a current direction reversal at ~2 V/nm, indicating a transition to the strong-field regime.
  • Demonstration that sub-optical-cycle Landau-Zener-Stückelberg interference governs electron dynamics in the strong-field regime, controllable by laser polarization.

Conclusions:

  • Monolayer graphene enables light-field control of electron dynamics on sub-optical-cycle timescales.
  • The observed phenomena are governed by coherent quantum interference effects.
  • These findings pave the way for applications in band-structure tomography and light-field-driven petahertz electronics.
