Research Description

Inhaled glucocorticoids are commonly prescribed to patients with chronic obstructive pulmonary disease (COPD), although their plieotropic anti-inflammatory function is not fully understood.

I am studying the mechanism by which glucocorticoids increase the uptake of apoptotic cells by alveolar macrophages - generally an anti-inflammatory stimulus - and how these changes may alter macrophage immune function in response to bacterial infection. I am particularly interested in how the combination of inhaled glucocorticoids and apoptotic cells within the lung (such as can be found in the lungs of many COPD and severe asthma patients) changes bacterial phagocytosis and immunopathology after Streoptococcal pneumoniae infection.
