Dr. Little is an Assistant Professor in the Department of Medicine. He attends on the Allergy Consultation Service as well as the Medical Intensive Care Unit and Pulmonary Consultation Service at Boston Medical Center . His outpatient activity is concentrated in the Adult Asthma and Allergy Clinics.

Dr. Little’s longstanding clinical interests and research efforts are focused on examining the nature of airway inflammation in allergic asthma, and translational approaches to diagnostics of allergic disease.

Prior to coming to Boston University, during a postdoctoral fellowship at the UCSF Cardiovascular Research Institute , he investigated the effect of causing an experimental cold in asthmatic and healthy volunteers, followed by concurrent examination of clinical asthma markers (e.g., spirometry, symptoms) and airway secretions by nasal lavage and sputum induction.

In the laboratory, he used key cytokine transgenic and knockout mice to investigate antigen-dependent and -independent allergic airway inflammation. Specifically, he investigated interleukin-16, a major CD4 ligand, as a paradigm for downregulation of antigen-dependent TH2 inflammation.

In his translational research Dr. Little served as a principal investigator in a clinic-based study to develop a rapid saliva diagnostics platform for determining the causes of deterioration in asthma control. This study has expanded to both Emergency Room populations at B.U. and cohorts of pediatric asthmatics in collaboration Dr. Elizabeth Matsui, Pediatric Allergy/Immunology at Johns Hopkins (now at UT Austin, TX). This translational approach has also been used in developing a point of care device to accurately and rapidly quantify allergen-specific IgE using component-resolved diagnostics. This latter effort is in collaboration with Drs. M. Selim Unlü in the Boston University College of Engineering.

He is also actively participating as a Co-Investigator in immunotherapy trials with the NIH-NIAID-funded Inner City Asthma Consortium, in collaboration with the BUMC site PI, Dr. George O’Connor.

Dr. Little’s educational and administrative responsibilities include directing the Boston University Allergy/Immunology Fellowship Training Program and being the Medical Director of the Pulmonary, Allergy and Sleep Clinics. He has also contributed to varied hospital-wide efforts involving Allergy and Pulmonary health, including developing protocols aimed at promoting antibiotic stewardship and directing BMC’s COPD Readmission Reduction Program in collaboration with BMC Strategy Team, Dr. Hasmeena Kathuria, and Alexis Gallardo-Foreman NP.

Toggle panel: Disable/Enable Visual Editor and Auto-Formatting
By default, WordPress automatically adds HTML code to your page whenever you press the Return (or Enter) key or whenever you insert a line break (you press Shift Return, etc.). This auto-formatting can cause layout problems, especially when you are creating forms. To disable auto-formatting, just check the box below and Save. This disables (for this page only) the auto-formatting feature in WordPress and the Visual Editor. This means you can edit this page only in HTML mode, but you have full control over the HTML code for this page.

To re-enable auto-formatting and the Visual Editor on this page, simply uncheck the box and Save.
