IL-27 Derived From Macrophages Facilitates IL-15 Production and T Cell Maintenance Following Allergic Hypersensitivity Responses.

Crosstalk between T cells, dendritic cells, and macrophages in temporal leukocyte clusters within barrier tissues provides a new concept for T cell activation in the skin. Activated T cells from these leukocyte clusters play critical roles in the efferent phase of allergic contact hypersensitivity (CHS). However, the cytokines driving maintenance and survival of pathogenic T cells during and following CHS remain mostly unknown.

Teledermatology: How It Is Impacting the Underserved.

The rapid mobilization of telemedicine during the COVID-19 pandemic has brought about renewed concern about the digital divide. Understanding the benefits and limitations of remote medical care is an ongoing process. Access to telemedicine appointments, as well as the experience of the virtual appointment itself, varies across demographic groups.
