Cis-regulatory Sequences02:02

Cis-regulatory Sequences

11.9K
Cis-regulatory sequences are short fragments of non-coding DNA that are present on the same chromosomes as the genes that they regulate. These fragments serve as binding sites for transcriptional regulators, proteins that are responsible for controlling gene transcription and differential gene expression across cell types in eukaryotes. Cis-regulatory sequences can be close to the gene of interest or thousands of bases away in the DNA sequence; however, those sequences that are further away are...

Global Regulatory Systems

731
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...

Autoimmune Disorders01:29

Autoimmune Disorders

1.9K
Autoimmune diseases are a group of disorders in which the body's immune system mistakenly attacks its own cells, tissues, and organs. This results from an overactive immune response against substances and tissues normally present in the body. Let's delve into the concept and mechanism of autoimmune diseases from an immune system point of view, explore different causes and examples of such diseases, and discuss potential solutions.

Second-Order Circuits01:17

Second-Order Circuits

3.6K
Integrating two fundamental energy storage elements in electrical circuits results in second-order circuits, encompassing RLC circuits and circuits with dual capacitors or inductors (RC and RL circuits). Second-order circuits are identified by second-order differential equations that link input and output signals.
Input signals typically originate from voltage or current sources, with the output often representing voltage across the capacitor and/or current through the inductor. For example, in...

Area of Science:

  • Immunology
  • Molecular Biology
  • Glycobiology

Background:

  • Autoimmune inflammation pathogenesis is complex, requiring identification of specific mediators for targeted therapies.
  • Galectins, a family of glycan-binding proteins, are crucial for immune cell balance.
  • Different galectins have opposing roles in inflammation, either promoting resolution or perpetuating autoimmune processes.

Purpose of the Study:

  • To explore the multifaceted roles of endogenous galectins and their glycosylated ligands in autoimmune responses.
  • To elucidate how galectin-glycan interactions influence immune circuits in autoimmunity.
  • To highlight the therapeutic potential of targeting galectin pathways in autoimmune diseases.

Main Methods:

  • Literature review and synthesis of current research on galectins in autoimmune inflammation.
  • Analysis of galectin function in immune homeostasis and disease pathogenesis.
  • Discussion of galectin-glycan interactions and their impact on immune regulation.

Main Results:

  • Galectins significantly shape autoimmune responses by modulating immune cell function.
  • Specific galectin-glycan interactions can either resolve or exacerbate inflammation.
  • These interactions offer insights into tolerance breakdown and immune circuit rewiring.

Conclusions:

  • Understanding galectin-glycan interactions is key to developing selective therapies for autoimmune diseases.
  • This knowledge can reveal new pathways of immune tolerance failure.
  • It may enable patient stratification and guide novel immune intervention strategies.
