cAMP-dependent Protein Kinase Pathways01:25

cAMP-dependent Protein Kinase Pathways

8.9K
Cyclic Adenosine Monophosphate (cAMP) is an essential second messenger that activates protein kinase A (PKA) and regulates various biological processes. A single epinephrine molecule binds to GPCR and activates several heterotrimeric G proteins, each stimulating multiple adenylyl cyclase, amplifying the signal, and synthesizing large numbers of cAMP molecules. Small changes in cAMP concentration affect PKA activity. The binding of four cAMP molecules induces a conformational change in PKA,...

Antimicrobial Proteins

15.2K
Antimicrobial proteins are important components of the immune system. They aid the body in combating pathogens by either killing them directly or hindering their replication processes. Four main types of antimicrobial substances are interferons, the complement system, iron-binding proteins, and antimicrobial proteins.
Interferons
Interferons (IFNs) are proteins produced by lymphocytes, macrophages, and fibroblasts infected with viruses. While IFNs cannot prevent viruses from entering and...

PI3K/mTOR/AKT Signaling Pathway01:22

PI3K/mTOR/AKT Signaling Pathway

6.1K
The mammalian target of rapamycin  (mTOR) is a serine/threonine kinase that regulates growth, proliferation, and cell survival in response to hormones, growth factors, or nutrient availability. This kinase exists in two structurally and functionally distinct forms: mTOR complex 1  (mTORC1) and mTOR complex 2  (mTORC2). The first form (mTORC1) is composed of a rapamycin-sensitive Raptor and proline-rich Akt substrate, PRAS40. In contrast,  mTORC2 consists of a...

mTOR Signaling and Cancer Progression

5.0K
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.
The mTOR pathway or the...

Global Regulatory Systems01:28

Global Regulatory Systems

838
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...

MAPK Signaling Cascades01:07

MAPK Signaling Cascades

9.0K
Mitogen-activated protein kinase, or MAPK pathway, activates three sequential kinases to regulate cellular responses such as proliferation, differentiation, survival, and apoptosis. The canonical MAPK pathway starts with a mitogen or growth factor binding to an RTK. The activated RTKs stimulate Ras, which recruits Raf or MAP3 Kinase (MAPKKK), the first kinase of the MAPK signaling cascade. Raf further phosphorylates and activates MEK or MAP2 Kinases (MAPKK), which in turn phosphorylates MAP...

  • Immunology

Background:

  • Host-pathogen interactions involve complex signaling pathways that determine infection outcomes.
  • Pathogens actively subvert host cell regulatory pathways, including energy metabolism, for their survival and proliferation.
  • AMP-activated protein kinase (AMPK) is a critical regulator of cellular energy homeostasis and plays a significant role in host-pathogen interactions.

Purpose of the Study:

Main Results:

  • Pathogens can either suppress or activate host AMPK to promote their own survival and replication.
  • Lower eukaryote AMPK orthologues are crucial for pathogen adaptation to the host environment.
  • Modulating AMPK activity, either pharmacologically or genetically, can significantly impact pathogen growth and persistence.

Conclusions:

  • Targeting host AMPK signaling represents a promising strategy for combating microbial infections.
  • Further research into pathogen-specific AMPK manipulation and host AMPK modulation is warranted.
  • Understanding the intricate interplay between host energy metabolism and pathogen survival is essential for developing novel therapeutics.
