Resumen
El cultivo extensivo de Artemisia desertorum en el desierto de Mu Us aumenta las alergias y el asma. El diagnóstico molecular identificó con precisión los perfiles de sensibilización, ayudando a predecir el riesgo de asma y mejorando el manejo del paciente.
Área de la Ciencia:
- Ciencias del medio ambiente Ciencias del medio ambiente.
- Alergia e Inmunología.
- Diagnóstico molecular El diagnóstico molecular es el diagnóstico molecular.
Sus antecedentes:
- El cultivo de Artemisia desertorum (mugwort del desierto) para el bloqueo del viento / fijación de arena en el desierto de Mu Us ha llevado a un aumento de las alergias al polen.
- La comprensión de la sensibilización al alérgeno es crucial para el manejo de los fenotipos alérgicos relacionados con las exposiciones ambientales.
Objetivo del estudio:
- Para realizar el diagnóstico molecular de alérgenos para las alergias al polen de Artemisia.
- Evaluar la utilidad del diagnóstico molecular en la caracterización de los perfiles de sensibilización de la inmunoglobulina E (IgE).
- Para vincular los perfiles de sensibilización a los fenotipos alérgicos, incluido el asma.
Principales métodos:
- Examinaron a 135 pacientes alérgicos a la Artemisia de regiones con una exposición al polen variable.
- Niveles de IgE cuantificados utilizando el ensayo ImmunoCAP para 11 alérgenos naturales o recombinantes de Artemisia.
Principales resultados:
- 134 pacientes mostraron una respuesta alérgica; los principales alérgenos incluyeron Art d 1, Art d 2, Art d 3, Art d 7 y Art d 9.
- Las regiones de alta exposición mostraron un sIgE elevado, una mayor sensibilización, una polisensibilización más amplia y una mayor prevalencia de asma.
- El asma se asoció de forma independiente con los alérgenos sensibilizados y los niveles de sIgE al extracto de mugwort y Art d 3; un modelo predictivo logró 0,832 AUC.
Conclusiones:
- La alta exposición al polen de A. desertorum eleva el riesgo de alergias y asma en el desierto de Mu Us.
- Los diagnósticos de alergia molecular con un panel completo de alérgenos mejoran la precisión del diagnóstico.
- Los diagnósticos moleculares ayudan a predecir la gravedad de la enfermedad e informan las estrategias de manejo clínico.

Proteins can undergo many types of post-translational modifications, often in response to changes in their environment. These modifications play an important role in the function and stability of these proteins. Covalently linked molecules include functional groups, such as methyl, acetyl, and phosphate groups, and also small proteins, such as ubiquitin. There are around 200 different types of covalent regulators that have been identified.

3.6K
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...

Asthma is a chronic pulmonary condition involving inflammation of the airways, hyper-reactivity, and reversible obstruction of the airways. This condition can significantly impact a person's quality of life, making breathing difficult and leading to distressing symptoms.
Asthma is classified as allergic and non-allergic. Allergens such as dust mites, pollen, and pet dander trigger allergic asthma, while factors like cold air, intense emotions, or exercise can induce non-allergic asthma.
