A one year follow-up on quality of adherent scars after autologous fat grafting processed by a filtration technique.

Autologous fat grafting (AFG), mostly in combination with adhesiolysis, has become the workhorse for reconstructing a dysfunctional or absent subcutaneous layer. In a previous study we showed that fat grafts isolated by centrifuging led to more than 20 % improvement in scar pliability. Nevertheless, there is still debate on which technique should be used to process and purify fat grafts.

RAG suppresses group 2 innate lymphoid cells.

Antigen specificity is the central trait distinguishing adaptive from innate immune function. Assembly of antigen-specific T cell and B cell receptors occurs through V(D)J recombination mediated by the Recombinase Activating Gene endonucleases RAG1 and RAG2 (collectively called RAG). In the absence of RAG, mature T and B cells do not develop and thus RAG is critically associated with adaptive immune function.

IL-33 potentiates histaminergic itch.

Background: Itch is a common symptom that can greatly diminish quality of life. Histamine is a potent endogenous pruritogen, and while antihistamines are often the first-line treatment for itch, in conditions like chronic spontaneous urticaria (CSU), many patients remain symptomatic while receiving maximal doses. Mechanisms that drive resistance to antihistamines are poorly defined.

Insights into atopic dermatitis pathogenesis lead to newly approved systemic therapies.

Atopic dermatitis (AD) is a common inflammatory skin disease characterized by scaly, oozing skin and itch. In moderate-to-severe AD, treatment options have been historically very limited and off-label use has been a common method for disease management. For decades, ciclosporin A was the only systemic immunosuppressive drug approved in most European countries to address this major unmet medical need.
