Here, we provide a demonstration of the suction blister cutaneous recall model. The model allows a simple access to study human in vivo adaptive immune responses, for instance in the context of vaccine development.

This protocol presents a method to assess pulmonary alveolar-capillary reserve measured by combined single-breath measurement of the diffusing capacity to carbon monoxide (D_L,CO) and nitric oxide (D_L,NO) during exercise. Assumptions and recommendations for using the technique during exercise form the foundation of this article.
