Interactions Between Signaling Pathways01:19

Interactions Between Signaling Pathways

7.2K
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

Bacterial Signaling01:30

Bacterial Signaling

40.1K
Bacterial signaling can occur within bacteria (intracellular) or between bacteria (intercellular). At times, a group of bacteria behaves like a community. To achieve this, they engage in quorum sensing, the perception of higher cell density that causes changes in gene expression. Quorum sensing involves both extracellular and intracellular signaling. The signaling cascade starts with a molecule called an autoinducer (AI). Individual bacteria produce AIs that move out of the bacterial cell...

What is Cell Signaling?

129.9K
Despite the protective membrane that separates a cell from the environment, cells need the ability to detect and respond to environmental changes. Additionally, cells often need to communicate with one another. Unicellular and multicellular organisms use a variety of cell signaling mechanisms to communicate to respond to the environment.

Oral Cavity01:11

Oral Cavity

3.0K
The oral cavity, or the mouth, is a complex structure in humans that plays a vital role in our day-to-day lives. Its role is not only in chewing and swallowing food; it also plays a role in speech and facial expressions.
Teeth: The teeth are the hardest structures in our bodies. Humans have two sets of teeth throughout their lifetime: deciduous (baby) teeth and permanent teeth. Each tooth consists of several parts: the crown (visible part), the root (embedded in the jaw), enamel (hard outer...

Area of Science:

  • Microbiology
  • Oral Biology
  • Microbial Ecology

Background:

  • Oral biofilms are complex ecosystems hosting diverse microbes.
  • Microbial interactions, including competition and cooperation, are crucial for biofilm structure and function.
  • Metabolic activities significantly influence the oral microenvironment and microbial community dynamics.

Purpose of the Study:

  • To provide a comprehensive overview of metabolic interactions within oral biofilms.
  • To highlight the importance of inter- and cross-kingdom microbial interactions.
  • To emphasize how these interactions shape the oral microbial community.

Main Methods:

  • Review of existing literature on oral microbial metabolic interactions.
  • Analysis of synergistic and antagonistic relationships between oral microbes.
  • Examination of cross-feeding, metabolic syntrophy, and cross-respiration mechanisms.

Main Results:

  • Metabolic interactions like cross-feeding and cross-respiration maintain biofilm homeostasis.
  • Bacterial metabolic activities can detoxify harmful compounds and provide essential nutrients.
  • Cross-kingdom interactions, including yeast-bacterial mutualism, influence colonization and pathogenesis.
  • Interspecies relationships are multidimensional and context-dependent.

Conclusions:

  • Metabolic interactions are fundamental to the structure, function, and health of oral biofilms.
  • Understanding these interactions is key to comprehending oral microbial community dynamics.
  • Studying microbes in isolation fails to capture the complexity of their social environment.
