Circadian Rhythms and Gene Regulation02:19

Circadian Rhythms and Gene Regulation

4.0K
The biological clock is involved in many aspects of regulating complex physiology in all animals. It was in 1935 when German zoologists, Hans Kalmus and Erwin Bünning, discovered the existence of circadian rhythm in Drosophila melanogaster. However, the internal molecular mechanisms behind the circadian clock remained a mystery until 1984, when Jeffrey C. Hall, Michael Rosbash, and Michael W. Young discovered the expression of the Per gene oscillating over a 24-hour cycle. In subsequent...

Biological Clocks and Seasonal Responses02:45

Biological Clocks and Seasonal Responses

34.6K
The circadian—or biological—clock is an intrinsic, timekeeping, molecular mechanism that allows plants to coordinate physiological activities over 24-hour cycles called circadian rhythms. Photoperiodism is a collective term for the biological responses of plants to variations in the relative lengths of dark and light periods. The period of light-exposure is called the photoperiod.

Infection01:20

Infection

7.9K
When a pathogen enters the body and reproduces, it can cause an infection, damage body cells, and cause illness symptoms that eventually lead to disease. Therefore, its prevention requires breaking the chain of infection.
The chain begins with pathogens: bacteria, viruses, fungi, prions, or parasites such as protozoa helminths. These can be present on the skin as transient or resident flora, or they can be acquired from the environment. Identifying and treating the type of infection and...

Bacterial Signaling01:30

Bacterial Signaling

32.0K
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...

Factors Affecting the Risk of Infection01:26

Factors Affecting the Risk of Infection

11.8K
The hosts' susceptibility to infection depends on several factors. The integrity of the skin and mucous membranes helps protect the body against microbial attacks. When the skin is altered, the chance of infection, limb loss, and even death increases.
The integrity and count of the white blood cells help the body resist pathogens and fight infection. When impaired, it reduces the body's resistance to pathogens. The acidic pH levels of the gastrointestinal, genitourinary tracts, and skin...

NF-κB-dependent Signaling Pathway02:26

NF-κB-dependent Signaling Pathway

7.4K
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.

Summary

Circadian rhythms, the body's 24-hour cycles, influence how pathogens interact with specific tissues. Understanding this host-pathogen interplay is key for developing new infectious disease treatments.

Area of Science:

  • Chronobiology
  • Infectious Diseases
  • Microbiology

Background:

  • Circadian rhythms are endogenous 24-hour cycles regulating physiological and behavioral processes in most organisms.
  • These rhythms operate at organismal, organ, and molecular levels, influencing cellular functions.
  • Pathogens, including parasites, bacteria, viruses, and fungi, can exhibit their own circadian rhythms or be affected by host rhythms.

Purpose of the Study:

  • To review the impact of circadian rhythms on host-pathogen interactions.
  • To explore how tissue-specific circadian biology influences pathogen dynamics within mammals.
  • To highlight the implications for infectious disease research and therapeutic strategies.

Main Methods:

  • Literature review of studies on circadian rhythms and pathogen-host interactions.
  • Analysis of research on tissue-specific circadian biology in mammals.
  • Synthesis of findings on how environmental and internal rhythms affect pathogens.

Main Results:

  • Circadian rhythms significantly influence the dynamics of host-pathogen relationships.
  • Pathogens adapt to or are modulated by the rhythmic microenvironments within specific host tissues.
  • Distinct organs possess unique circadian characteristics that impact pathogen colonization and replication.

Conclusions:

  • The interplay between mammalian circadian biology and pathogen behavior is complex and tissue-dependent.
  • Circadian rhythms represent a critical factor in understanding infectious disease susceptibility and progression.
  • Targeting circadian pathways offers a potential novel approach for combating infectious diseases.
