RNA Stability01:53

RNA Stability

33.5K
Intact DNA strands can be found in fossils, while scientists sometimes struggle to keep RNA intact under laboratory conditions. The structural variations between RNA and DNA underlie the differences in their stability and longevity. Because DNA is double-stranded, it is inherently more stable. The single-stranded structure of RNA is less stable but also more flexible and can form weak internal bonds. Additionally, most RNAs in the cell are relatively short, while DNA can be up to 250 million...

Fixed Action Patterns01:06

Fixed Action Patterns

16.0K
A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

Robbers Cave04:49

Robbers Cave

14.3K
During the 1950s, the landmark Robbers Cave experiment demonstrated that when groups must compete with one another, intergroup conflict, hostility, and even violence may result. At the Oklahoman summer camp, two troops of boys—termed the Rattlers and the Eagles—took part in a week-long tournament. During this time, their negativity culminated in derogatory name-calling, fistfights, and even vandalism and destruction of property. However, this work also revealed that such tension...

Social Traps01:41

Social Traps

22.3K
Social traps are negative situations where people get caught in a direction or relationship that later proves to be unpleasant, with no easy way to back out of or avoid. The concept was orignally introduced by John Platt who applied psychology to Garrett Hardin's "Tragedy of the Commons", where in New England herd owners could let their cattle graze in the common ground. This situation seems like a good idea, but an individual could have an advantage. If they owned...

Instinctive Drift01:05

Instinctive Drift

221
Instinctive drift refers to the tendency of animals to revert to their innate behaviors despite repeated reinforcement. Breland and Breland demonstrated this concept in an experiment with a raccoon. The raccoon was trained to pick up two coins and place them in a container in exchange for food. Initially, the raccoon learned to associate the coins with food, making them a conditioned stimulus or a substitute for food. However, over time, the raccoon became less willing to put the coins into the...

SN1 Reaction: Stereochemistry02:15

SN1 Reaction: Stereochemistry

8.5K
This lesson provides an in-depth discussion of the stereochemical outcomes in an SN1 reaction.
In the first step of an SN1 reaction, the bond between the electrophilic carbon and the leaving group ionizes to generate the carbocation intermediate. The second step of the mechanism is the nucleophilic attack.
In the formed carbocation, the positively charged carbon is sp2 hybridized with a trigonal planar geometry. As all the three substituents lie on the same plane, a plane of symmetry for the...

Summary

Glycated RNAs on neutrophils promote their adhesion to blood vessel walls and movement to inflammation sites. This finding reveals a new mechanism for neutrophil recruitment during inflammatory responses.

Area of Science:

  • Immunology
  • Molecular Biology
  • Cell Biology

Background:

  • Neutrophils are key immune cells involved in inflammation.
  • Endothelial adhesion and extravasation are critical steps in neutrophil recruitment.
  • The molecular mechanisms governing these processes are not fully understood.

Purpose of the Study:

  • To investigate the role of glycated RNAs in neutrophil adhesion and extravasation.
  • To elucidate the molecular interactions between neutrophils and the endothelium mediated by glycated RNAs.

Main Methods:

  • Analysis of RNA glycation in neutrophils.
  • In vitro assays for neutrophil-endothelial cell adhesion.
  • In vivo models of inflammation to study extravasation.

Main Results:

  • Glycated RNAs were identified on the surface of neutrophils.
  • These glycated RNAs were found to mediate neutrophil adhesion to endothelial cells.
  • Blocking glycated RNAs reduced neutrophil extravasation to inflammatory sites.

Conclusions:

  • Glycated RNAs on neutrophils are critical for their adhesion to the endothelium.
  • This mechanism plays a significant role in neutrophil recruitment to sites of inflammation.
  • Targeting glycated RNAs could offer novel therapeutic strategies for inflammatory diseases.
