The primary objective of this study is to investigate the contribution of group 2 innate lymphoid cells (ILC2s) to the immunologic mechanisms of chronic airway diseases.

The primary purpose of this study is to investigate the cytokine responses of blood ILC2s from preterm children by collecting peripheral blood at age 5-10 years from children born either preterm or at term, and to analyze the functions of their circulating ILC2s in vitro.

This study is being done to identify potential donors for on-going research on eosinophils, a white blood cell. Eosinophils are involved in various human diseases such as allergic diseases and bronchial asthma.

This research study is being done for people who have asthma and chronic rhinosinusitis, hay fever, or you do not have any sinus disease, asthma or hay fever (control). The aim of the study is to investigate the functions of nasal epithelial cells.

The purpose of this study is to systematically analyze the function of various immune cells in the esophagus, we need to perform a series of preliminary pilot studies on sections of esophageal biopsy specimens to optimize experimental conditions, examine the feasibility of several new cell biologic and immunologic techniques, and obtain preliminary data to estimate statistical parameters (e.g. individual variability and standard deviation). 

The purpose of this study is to measure the presence of follicular T cells in the peripheral blood of people who have a nasal allergy response to ragweed.

The purpose of this study is to identify a new population of cells in the blood that may be contributing to allergic inflammation in atopic asthmatics.
