Summary
Severe asthma treatment advances with targeted therapies for eosinophilic inflammation. Further research is needed to address non-type-2 pathways and achieve personalized patient care for all severe asthma cases.
Area of Science:
- Pulmonology
- Immunology
- Pharmacology
Background:
- Severe asthma is heterogeneous, with inflammation phenotypes guiding treatment.
- Type-2 cytokine pathways are key drivers of eosinophilic inflammation in severe asthma.
- Targeting these pathways has improved treatment but not eradicated symptoms or exacerbation risk.
Purpose of the Study:
- To review progress in clinical assessment and management of severe asthma.
- To highlight challenges and unmet needs in severe asthma care.
- To emphasize the goal of individualized patient care for severe asthma.
Main Methods:
- Review of clinical assessment strategies.
- Analysis of biomarker profiling for treatment selection.
- Evaluation of comorbid factors in severe asthma management.
- Exploration of immunobiology and therapeutic targets.
Main Results:
- Sputum eosinophilia identified corticosteroid responsiveness, initiating phenotyping.
- Targeted therapies for type-2 pathways have transformed severe asthma treatment.
- Current treatments necessitate further investigation into non-type-2 mechanisms.
Conclusions:
- Individualized care for severe asthma requires robust clinical evaluation and biomarker assessment.
- Further research into non-type-2 pathways is crucial for comprehensive severe asthma management.
- Achieving personalized patient care remains an ongoing goal in severe asthma.

01:29Asthma-I: Introduction
3.4K
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...

4.2K
Asthma is a prevalent chronic respiratory condition marked by inflammation and hyperresponsiveness of the airways. Its pathophysiology involves complex interactions among inflammatory pathways, immune responses, and neural mechanisms.
Additionally, environmental and genetic factors play crucial roles in determining an individual's susceptibility to asthma and the severity of their condition.
Critical processes in asthma pathophysiology include:

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.

01:37Energy to Drive Translocation
2.7K
Mitochondrial protein import is powered by two distinct energy sources: ATP hydrolysis and electrochemical potential across the inner membrane. Newly synthesized precursors are bound by cytosolic chaperones of the Hsp70 family, which guide them to the import receptors on the mitochondrial surface. Utilizing the energy of ATP hydrolysis, Hsp70 chaperones transfer these precursors to the TOM receptors on the mitochondrial outer membrane.
