Development of Human Microbiota01:30

Development of Human Microbiota

58
The human microbiota begins developing at birth and undergoes continual change as we age. Infancy marks a critical period of microbial sensitivity, offering a “window of opportunity” during which beneficial microbes help mature the immune system. By age three, children typically develop a more stable and diverse microbial community. Newborns acquire microbes from their immediate environment; vaginal delivery favors maternal vaginal microbes, while cesarean births favor microbes from...

Microbiota of the Respiratory Tract01:29

Microbiota of the Respiratory Tract

52
The human respiratory tract, comprising the upper and lower segments, serves as a critical interface with the external environment. The upper respiratory tract (URT)—including the nostrils, sinuses, pharynx, and oropharynx—is heavily colonized by microbes, while the lower respiratory tract (LRT), composed of the larynx, trachea, bronchi, and lungs, was long thought to be sterile. However, recent molecular studies have revealed that the lungs are not devoid of microbes but act more...

Asthma I: Introduction01:28

Asthma I: Introduction

69
Asthma is a chronic inflammatory disorder of the airways characterized by variable airflow obstruction and heightened bronchial responsiveness to a wide range of triggers. The underlying inflammation leads to airway swelling, mucus hypersecretion, and smooth muscle constriction, all of which narrow the airway lumen and impede airflow. Clinically, asthma presents with recurrent episodes of wheezing, shortness of breath, chest tightness, and coughing, symptoms that typically vary in intensity and...

Introduction to the Human Microbiota

138
Microorganisms colonize various regions of the human body, including the mouth, nasal passages, throat, stomach, intestines, urogenital tract, and skin. The total number of microbial cells is estimated to range from 10¹³ to 10¹⁴—comparable to, or exceeding, the number of human somatic cells. This host–microbiome relationship has led to the conceptualization of humans as supraorganisms, wherein microbial communities perform vital roles in development, immunity,...

Asthma-I: Introduction

3.5K
Asthma is a chronic respiratory ailment that requires careful management due to its varying symptoms and influencing factors. It is characterized by airway inflammation, bronchial hyperresponsiveness, and reversible airflow obstruction, leading to symptoms like wheezing, shortness of breath, chest tightness, and coughing. The symptom frequency and intensity may vary considerably over time. It is also linked to immune system responses to allergens and irritants, highlighting the complex...

Area of Science:

  • Immunology
  • Environmental Health
  • Genetics

Background:

  • Allergic disease prevalence has significantly increased globally.
  • Complex interactions between genetic predisposition and environmental exposures are implicated.
  • Key environmental factors include air pollution, microbiota, and climate change.

Purpose of the Study:

  • To review the interplay of genetic and environmental factors in allergic disease development.
  • To highlight the role of environmental exposures in immune response regulation.
  • To emphasize the importance of early interventions for susceptible populations.

Main Methods:

  • Literature review of recent research on allergic diseases.
  • Analysis of interactions between environmental factors and genetic susceptibility.
  • Exploration of immune system regulation in the context of allergies.

Main Results:

  • Environmental factors critically influence immune responses, particularly in genetically susceptible individuals.
  • Interactions between genetics and environment are central to allergy development.
  • Evidence supports the role of air pollution, microbiota, and climate change.

Conclusions:

  • Understanding gene-environment interactions is key to addressing the allergy epidemic.
  • Early identification and implementation of preventive strategies are essential.
  • Further research is needed to identify effective interventions for allergy prevention.
