The effector function of CD4 T cells is critically dependent on their ability to rapidly enter and traverse a wide variety of peripheral tissues to survey for damage, locate foci of infection, or cause pathology from chronic infection or autoimmunity. While the processes of homing to inflamed sites1-4 and extravasation5-7 from the vasculature into tissues have been well-characterized, the factors that drive and regulate the interstitial motility of T cells remain undefined. The migration of T cells in complex 3D environments has been studied in vitro through the use of artificial matrices8-10 or microfluidic devices11,12, but these fail to recapitulate the complex and dynamic environment of an in vivo system. It is only recently, with the advent of high-resolution multi-color intravital imaging that it has become possible to study the dynamic behavior of immune cells in situ, allowing for a better understanding of intact immune responses.
Over a decade ago, several influential studies were published that first utilized multiphoton microscopy to address immunological questions. Early studies focused on the behavior of immune cells within explanted lymphoid organs13-16, which were soon followed by techniques to image exposed lymph nodes in anesthetized mice17. Imaging allowed for new fundamental observations about the stages of lymph node priming of T cells18, the mechanisms by which T cells migrate in secondary lymphoid organs19, T cell interactions with other immune cells20,21, and dynamic T cell positioning within the lymph node22. Although many early studies focused on lymph node dynamics, intravital imaging has been since been utilized to image the immune response in many peripheral tissues, including the brain23-25, liver26, lung27, and skin28-30. 
The mouse ear dermis is particularly well poised for imaging, due to the thinness of ear skin, a relative lack of hair, and the ease with which it can be isolated from respiratory movements31. Indeed, the ear dermis has been used to image the interstitial behavior of dendritic cells32,33, T cells28,29,34,35, and neutrophils36,37, and is a well-established site for studying dermal inflammation. Increasingly, non-invasive procedures have been replacing surgical preparations of the skin, including split dermis38,39, flank39,40, or dorsal skin flap window39,41 models, that can induce changes to the local inflammatory milieu. The use of transferred, in vitro-primed, antigen-specific CD4 effector T cells allows for the study of a homogenous population of cells in the context of a dermal inflammatory response30. Here we describe a non-invasive imaging procedure that allows for the visualization of antigen-specific effector CD4 T cells in the dermal interstitium of the inflamed mouse ear, and the ability to manipulate these cells in real-time by introducing blocking antibodies through a venous catheter. We show that this model is effective for tracking the movement of CD4 T cells in the dermis and for querying the mechanisms that govern this motility.
