The Tumor Microenvironment02:17

The Tumor Microenvironment

7.3K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

Surface Membrane Barriers01:18

Surface Membrane Barriers

2.1K
The skin and mucous membranes serve as the primary line of defense against pathogens by providing both physical and chemical protection. These barriers are essential in preventing the entry and establishment of microbes, thereby maintaining the integrity of the host.
The outer layer of the skin, the epidermis, is a robust barrier comprising layers of closely packed keratinized cells. This dense arrangement prevents microbes from penetrating the body. The periodic shedding of epidermal cells...

Factors Affecting the Risk of Infection

13.1K
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...

Anatomy of the Intestines

85.8K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Microorganisms in Medicine and Therapeutics

Microorganisms play a fundamental role in vaccine development, gene therapy, and therapeutic production. Their biological properties are harnessed to advance medicine and public health. Beyond immunization, microorganisms contribute to gut health, antibiotic synthesis, and genetic disease treatment.Live Attenuated and Inactivated VaccinesLive attenuated vaccines, such as the measles, mumps, and rubella (MMR) vaccine, utilize weakened forms of pathogens to closely resemble natural infections.

Defense Mechanism Against Infection01:26

Defense Mechanism Against Infection

8.2K
Natural flora, body system defenses, and inflammation are natural barriers of the body against infectious agents regardless of previous exposure. Normal floras of the human body refer to the microbial population that colonizes the skin and mucous membranes.
In addition, many body organ systems have unique defenses against infection. The skin is an intact, multilayered surface preventing invasion by microorganisms unless impaired. Mucous membranes lining the mouth, nose, and eyelids are barriers...

Area of Science:

  • Gynecology
  • Microbiology
  • Oncology

Background:

  • Persistent human papillomavirus (HPV) infection is a primary cause of cervical cancer.
  • The female genital tract microbiome, typically dominated by lactobacilli, can be disrupted by various factors.
  • Emerging evidence suggests the vaginal microbiome plays a significant role in HPV infection natural history and clinical impact.

Purpose of the Study:

  • To review current knowledge on vaginal microbiome alterations in women with HPV infection and cervical disease.
  • To discuss the potential functional interplay between specific bacterial groups and HPV infection outcomes.
  • To highlight the need for further research into the role of specific bacteria in HPV-associated pathologies.

Main Methods:

  • Literature review of high-throughput studies on female genital tract bacterial diversity and abundance.
  • Analysis of studies investigating changes in vaginal microbiome composition in women with HPV and cervical lesions.
  • Synthesis of current understanding regarding the interplay between vaginal bacteria and HPV infection outcomes.

Main Results:

  • Changes in vaginal microbiome composition are detected in women with HPV infections and HPV-associated lesions/cancer.
  • Disruption of the natural lactobacilli-dominant microbiome can favor the outgrowth of other bacteria, potentially influencing pathological states.
  • The specific roles of bacterial groups in the development, progression, prevention, or regression of HPV-associated pathologies remain incompletely understood.

Conclusions:

  • The vaginal microbiome is a critical factor influencing the natural history and clinical outcomes of HPV infections.
  • Further research is needed to elucidate the precise mechanisms by which specific bacteria interact with HPV and affect cervical disease.
  • Understanding these interactions may lead to novel diagnostic or therapeutic strategies for HPV-related cervical diseases.
