Cell Signaling Feedback Loops01:07

Cell Signaling Feedback Loops

6.6K
Positive and negative feedback loops are crucial for regulating biological signaling systems. These feedback loops are processes that connect output signals to their inputs.
Negative feedback loops
Most signaling systems have negative feedback loops that can perform different functions such as output limiter, and adaptation.
Output limiter
Upon receiving an input signal, the cellular response rapidly increases until a threshold is reached. Beyond this threshold, a negative feedback loop...

Positive and Negative Feedback Loops

20.2K
Animal organs and organ systems constantly adjust to internal and external changes through a process called homeostasis ("steady state"). Examples of these changes include regulation of the level of glucose or calcium in the blood or internal responses to external temperatures. Homeostasis requires  maintaining an internal dynamic equilibrium:

Cells of the Innate Immune Response01:28

Cells of the Innate Immune Response

3.8K
The innate immune response is an immediate and non-specific response against pathogens, acting swiftly to prevent the spread of infections. The primary cells involved in this response are phagocytes and natural killer (NK) cells.
Phagocytes
Phagocytes police the peripheral tissues by removing cellular debris and responding to the invasion of foreign substances or pathogens. Many phagocytes attack and remove microorganisms even before lymphocytes detect them. The human body has two general...

NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

7.9K
The transcription factor NF-κB was discovered in 1986 in the lab of Nobel laureate Professor David Baltimore, for its interaction with the immunoglobulin light chain enhancer in B-cells. After more than three decades of study, it is now evident that NF-κB regulates the expression of over 100 genes. Most of these genes play an essential role in the innate and adaptive immune responses as well as the inflammatory responses of animals.

Introduction to Innate and Adaptive Immunity

5.4K
The human immune system is a complex defense mechanism that protects the body from harmful pathogens and foreign substances. It comprises two crucial components: innate and adaptive immunity.
Innate immunity is the body's natural, nonspecific defense system that acts quickly to protect against pathogens. It incorporates physical barriers like skin and mucous membranes and cellular elements such as phagocytes and natural killer cells. This part of our immune system provides an immediate,...

Immune Surveillance by NK Cells and Phagocytes01:25

Immune Surveillance by NK Cells and Phagocytes

3.4K
Immune surveillance is an integral part of the innate immune system, involving the continuous monitoring of peripheral tissues to detect and respond to pathogens, infected cells, or cancerous cells. This surveillance is conducted primarily by natural killer (NK) cells and phagocytes, which employ distinct but complementary mechanisms to identify and eliminate threats.
Natural Killer Cells: The Fast Responders
NK cells are large granular lymphocytes found in the blood and lymphatic system. These...

Area of Science:

  • Molecular Biology
  • Immunology
  • Cell Biology

Background:

  • Krüppel-like factors (KLFs) are transcription factors regulating diverse cellular processes.
  • KLFs are crucial for myeloid cell differentiation and function during hematopoiesis.
  • KLF4, KLF2, KLF3, and KLF6 are particularly important in macrophage inflammatory signaling.

Purpose of the Study:

  • To review the cooperative and competitive roles of KLFs in regulating macrophage inflammatory responses.
  • To explore how KLFs influence the initiation and resolution of inflammation.
  • To discuss the potential involvement of KLFs in the pathogenesis of chronic inflammatory conditions.

Main Methods:

  • Literature review of studies on KLF function in macrophages.
  • Analysis of gene expression data related to KLFs and inflammatory pathways.
  • Synthesis of current understanding of KLF-mediated transcriptional regulation in inflammation.

Main Results:

  • KLFs act as critical regulators, either activating or repressing target genes involved in inflammation.
  • KLF4 plays a central role in macrophage development and inflammatory signaling.
  • Interactions between different KLFs dictate the balance of pro- and anti-inflammatory responses.

Conclusions:

  • KLFs are central players in orchestrating macrophage inflammatory responses.
  • Dysregulation of KLF activity may contribute to the development of chronic inflammatory diseases.
  • Targeting KLFs could offer therapeutic strategies for inflammatory conditions.
