Summary
Antimicrobial peptides, like human cathelicidin (hCAP-18/LL-37), are vital for innate immunity and have diverse therapeutic applications. This review details hCAP-18/LL-37
Area of Science:
- Innate immunity and host defense mechanisms.
- Molecular and cellular immunology.
- Antimicrobial peptide research.
Background:
- Antimicrobial peptides (AMPs) are crucial components of the innate immune system.
- The cathelicidin family, including human cathelicidin (hCAP-18/LL-37), is evolutionarily conserved.
- hCAP-18/LL-37 is the sole identified human cathelicidin with broad physiological roles.
Purpose of the Study:
- To review the multifaceted roles of the cathelicidin hCAP-18/LL-37.
- To examine its significance in lung physiology and defense.
- To explore its potential as a therapeutic agent.
Main Methods:
- Literature review of existing studies on hCAP-18/LL-37.
- Analysis of research on cathelicidin functions beyond antimicrobial activity.
- Evaluation of therapeutic potential in various disease models.
Main Results:
- Cathelicidins exhibit diverse functions, including antimicrobial and lipopolysaccharide-neutralizing effects.
- These peptides significantly influence both innate and adaptive immunity.
- hCAP-18/LL-37 plays a critical role in lung defense mechanisms.
Conclusions:
- Antimicrobial peptides, particularly hCAP-18/LL-37, are promising therapeutic candidates.
- Their applications are being explored for conditions like oral mucositis, cystic fibrosis, and septic shock.
- Further research into hCAP-18/LL-37's role in lung health is warranted.

01:26Defense Mechanism Against Infection
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...

01:18Surface Membrane Barriers
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...

01:23Antimicrobial Proteins
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...

01:31Defense Against Bacterial Pathogens
The human immune system is a complex network of cells, tissues, and organs that work together to defend the body against bacterial infections. It consists of various immune cells, each playing a specific role in the defense mechanism.
Phagocytes
Phagocytes are the frontline soldiers of the immune system. They include neutrophils and macrophages. Neutrophils are the most abundant type of white blood cell and are quickly mobilized to the site of infection. Macrophages are larger cells that patrol...

01:29Microbiota of the Respiratory Tract
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 like...
01:29Pneumonia I: Introduction
Pneumonia is an infection of the lower respiratory tract that leads to inflammation of the lung parenchyma, often resulting in the accumulation of inflammatory exudate in the alveoli and airways. Unlike the watery, low-protein fluid exudate in pulmonary edema, the exudate in this case is a thick fluid rich in immune cells, proteins, and debris produced during infection and inflammation.This impairs gas exchange and can lead to consolidation of lung tissue. The infection may be caused by a...
