Resumen
Los microbios de la piel pueden modificarse para crear nuevas vacunas tópicas. Esta investigación explora la ingeniería de la microbiota de la piel para el desarrollo de vacunas, ofreciendo un nuevo enfoque para la inmunización.
Área de la Ciencia:
- Microbiología
- Inmunología
- Biotecnología
Sus antecedentes:
- La piel alberga una comunidad diversa de microorganismos conocidos como microbiota cutánea.
- La microbiota de la piel juega un papel crucial en el mantenimiento de la salud y la inmunidad de la piel.
- Las estrategias de vacunación actuales implican principalmente la administración sistémica, lo que puede conducir a efectos secundarios.
Objetivo del estudio:
- Investigar el potencial de la ingeniería de la microbiota de la piel para la administración de vacunas.
- Explorar un nuevo enfoque para el desarrollo de vacunas tópicas.
- Evaluar la viabilidad del uso de microbios residentes en la piel como plataforma para la inmunización.
Principales métodos:
- Modificación genética de bacterias comensales específicas de la piel.
- Desarrollo de bacterias diseñadas para expresar antígenos de vacunas.
- Aplicación tópica de bacterias modificadas en la piel.
- Evaluación de las respuestas inmunológicas y la eficacia protectora en modelos preclínicos.
Principales resultados:
- Ingeniería exitosa de bacterias de la piel para expresar y presentar antígenos extraños.
- Demostración de estimulación inmune localizada tras la aplicación tópica.
- Evidencia de inmunidad protectora contra los patógenos del reto en sujetos tratados.
- La plataforma de microbiota de la piel diseñada mostró un perfil de seguridad favorable.
Conclusiones:
- La microbiota cutánea representa una plataforma viable para el desarrollo de vacunas tópicas eficaces.
- La ingeniería de microbios de la piel residentes ofrece una nueva vía prometedora para las estrategias de vacunación.
- Este enfoque podría conducir a métodos de inmunización más seguros y más específicos.

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.

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...

Skin is the first line of defense and encounters a variety of microbes. Some pathogenic strains are often the cause of a broad range of infections of the skin and other body systems. These conditions can affect people of all ages and may have different causes, including genetic factors, infections, autoimmune reactions, environmental factors, and lifestyle choices.

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...

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...

Epidermal stem cells (EpiSCs) are mainly located at the basal layer of the epidermis. These cells repair minor injuries of the skin and replace dead skin cells. However, EpiSCs’ cannot heal severe wounds such as major burns or those from diabetes or hereditary disorders. In such cases, culturing the epidermal stem cells from the patient is possible and has yielded successful treatment options, such as laboratory-grown skin grafts. These grafts are synthesized using a patient’s own...
