Objectives. This study was conducted to determine whether patients with allergy might be more susceptible to human rhinovirus (HRV) infection and whether the effects of infection on the elicited immune responses are different in allergic and non-allergic patients with chronic rhinosinusitis (CRS). Methods. Uncinate process tissues were obtained from 61 chronic rhinosinusitis patients (of which, 39 had allergy and 22 did not) who were infected with HRV-16 using an air-liquid interface organ culture system. The expression levels of programmed cell death-ligand (PD-L)1, PD-L2, intracellular adhesion molecule 1 (ICAM-1), IFN-

Validation Tests

Abstract Standard tests are needed for evaluating and comparing the mechanical and biological functions of tissue engineered arteries and other vascular grafts. We propose an ex vivo organ culture system as a living system for testing tissue-engineered vascular grafts. This bench-top organ culture system mimics the physiological environment of arteries including the flow, pressure, and the axial stretch. Arterial mechanical properties and physiologic functions including compliance, burst pressure, and contractile functions can be assessed before an expensive long-term animal test is initiated. Test results of natural arteries indicate that organ culture is a valid model for comprehensive evaluation of tissue-engineered vascular grafts.

Physiological Flow

Abstract To study the effect of axial stretch on vascular function and wall remodeling, porcine carotid arteries were cultured under conditions of physiological flow and elevated axial stretch in an ex vivo organ culture system. Smooth muscle cell proliferation was measured by bromodeoxyuridine index. Results showed that cell proliferation was significantly increased in the highly stretched arteries when compared to the normally stretched arteries. This may indicate the feasibility of stimulating new arterial growth by stretching natural arteries.
