Gene Regulation in Microbial Communities: Quorum Sensing01:28

Gene Regulation in Microbial Communities: Quorum Sensing

Quorum sensing is a mechanism of bacterial communication that enables coordinated gene expression in response to changes in population density. This facilitates collective behaviors that enhance survival, resource acquisition, and ecological adaptation. This process relies on small signaling molecules called autoinducers that accumulate as bacterial populations grow. When a critical threshold concentration of autoinducers is reached, bacterial cells collectively modify gene expression,...
Global Regulatory Systems01:28

Global Regulatory Systems

Global regulatory systems in bacteria enable rapid and coordinated responses to environmental changes by integrating sensory inputs with gene expression, ensuring efficient adaptation to fluctuating conditions. Key global regulatory mechanisms include regulons, two-component systems, sigma factors, and secondary messengers.Regulons and Global RegulatorsA regulon is a collection of genes and operons controlled by a common global regulator. These regulators enable bacteria to prioritize resource...
Relationship Formation02:12

Relationship Formation

What do you think is the single most influential factor in determining with whom you become friends and whom you form romantic relationships? You might be surprised to learn that the answer is simple: the people with whom you have the most contact. This most important factor is proximity. You are more likely to be friends with people you have regular contact with. For example, there are decades of research that shows that you are more likely to become friends with people who live in your dorm,...
Cooperative Binding of Transcription Regulators02:13

Cooperative Binding of Transcription Regulators

Transcriptional regulators bind to specific cis-regulatory sequences in the DNA to regulate gene transcription. These cis-regulatory sequences are very short, usually less than ten nucleotide pairs in length. The short length means that there is a high probability of the exact same sequence randomly occurring throughout the genome.  Since regulators can also bind to groups of similar sequences, this further increases the chances of random binding. Transcriptional regulators form dimers that...

Social Exchange Theory02:06

Social Exchange Theory

We have discussed why we form relationships, what attracts us to others, and different types of love. But what determines whether we are satisfied with and stay in a relationship? One theory that provides an explanation is social exchange theory. According to social exchange theory, we act as naïve economists in keeping a tally of the ratio of costs and benefits of forming and maintaining a relationship with others (Rusbult & Van Lange, 2003).

Summary
This summary is machine-generated.

We developed a framework to regulate information spread in social networks by tuning interventions within and between communities. This approach identifies low-cost strategies for effective containment, revealing distinct diffusion regimes.

Area of Science:

  • Complex systems science
  • Network science
  • Information diffusion modeling

Background:

  • Effective regulation of information diffusion in social systems is crucial but challenging.
  • The interplay between network community structure and targeted interventions is not well understood.

Purpose of the Study:

  • To develop a framework integrating community structure and regulation for analyzing information diffusion.
  • To understand how tuning interventions within and across communities affects information spread.

Main Methods:

  • Developed the community structure-regulation coupling framework (COSREF).
  • Analyzed the interplay between network topology and two regulation parameters (within- and cross-community transmission).
  • Validated predictions using simulations and analyses of large real-world social networks.

Main Results:

  • Identified three distinct diffusion regimes: no, localized, and global diffusion, separated by abrupt transitions.
  • Revealed a low-cost intervention region enabling containment with small, targeted adjustments.
  • Demonstrated the framework's robustness across different network topologies.

Conclusions:

  • The structure-regulation perspective offers general principles for efficient and robust regulation of modular systems.
  • COSREF unifies network topology and regulation within a single theoretical setting.
  • The findings are applicable to real-world information environments and intervention strategies.
