Q

What are the main inflammatory cells in the airway??

A
  1. Mast cells: These are the key cell of the innate immune system. They produce a variety of pre-formed and newly-formed inflamatory mediators.
  2. B lymphocytes: These produce antigen specific IgE (immunoglobulin E), in response to stimulation by interleukin-4 and interleukin-13 cytokines.

Of less importance….

  1. Dendritic cells - Antigen presenting cells.
  2. Epithelial cells - Secrete pro-inflammatory mediators (Thymic stromal lymphopoietin)
  3. Macrophages - Also express receptors which bind IgE and IgG

Q

What is the hygiene hypothesis?

A

It is hypothesized that exposure to certain microbes by early infection or from the environment may drive T cell production** towards the non atopic (Th 1)** phenotype, thereby reducing the occurence of Asthma.

Q

Which drug should an Asthmatic taking Salbutamol not be taking, and why?

A
  • What: Beta-Blockers (i.e. Atenolol)
  • Why: Salbutamol is a Beta-Agonist. Beta-blockers are Beta-Antagonists. These drugs will be acting in opposition, rendering them both ineffective.

Q

What is Omalizumab used for?

Q

Why does Omalizumab not help obese asthmatics?

A
  • IgE (immunoglobulin E) is an inflammatory mediator released in atopic asthma.
  • Omalizumab blocks production of IgE.
  • Asthma caused by obesity does not trigger IgE release as part of an immune cascade.
  • This monoclonal antibody anti-IgE treatment will therefore be ineffective.

Q

How does Omalizumab work?

A
  • Binds to free Ige (Immunoglobulin E), decreasing the amount of cell bound IgE
  • Decreases expression of receptors that have a high affinity for IgE (i.e. FceRI receptors)
  • Decreases the amount of inflammatory mediators released by cells such as mast cells, Basophils, or Eosinophils.
  • These collectively decrease allergic inflammation, and prevent exacerbation of asthma.

What is the **definition** of **Asthma**?
"Asthma is a chronic inflammatory disorder of the airways in which many cells and cellular elements play a role.

These episodes are usually associated with widespread but variable airflow obstruction that is often reversible either spontaneously or with treatment."

107
Week 210 Why does the tongue deviate after a **Hypoglossal nerve injury**?
Upon protrusion, the tongue will deviate TOWARD the side of the LMN lesion (i.e., same side). This is due to the **unopposed action of the genioglossus muscle on the normally innervated side of the tongue** (the genioglossus **pulls the tongue forward**).
