- Children with cancer suffer from symptoms and burdensome treatments that often cause distress to children and their families. Mortality is one aspect of cancer diagnosis, while another is the quality of life and well-being during and after the treatment. By supporting children's communication, self-efficacy and coping ability in the care situation, children are given the possibilities for increased independence and participation and are allowed to develop an influence over their care. The aim of this study was to develop and evaluate the feasibility and acceptability of an adult-facilitated pretend play intervention for children with cancer. Five children with ongoing treatment for cancer were invited to a play intervention that consisted of six to eight sessions of structured pretend play aimed at increasing participation, independence, and well-being. A mixed method design was used to evaluate the feasibility and acceptability of the play intervention. Measures were collected before and after interventions, and in conjunction with every play session. Results suggest that the children enjoyed the play intervention. Findings indicate small improvements regarding self-efficacy in care situations and equal or increased quality of life for participants. A main finding was that no adverse events or increased worrying was reported in conjunction with play sessions. Therefore, the intervention is regarded as safe, feasible, and acceptable as reported by participants and their primary caregivers and a possible means of increasing participation and independence in children with a cancer diagnosis.

- Fibroblastic reticular cells (FRCs) are stromal cells that actively promote the induction of immune responses by coordinating the interaction of innate and adaptive immune cells. However, whether and to which extent immune cell activation is determined by lymph node FRC reprogramming during acute viral infection has remained unexplored. Here, we genetically ablated expression of the type I interferon-α receptor (Ifnar) in Ccl19-Cre+ cells and found that sensing of type I interferon imprints an antiviral state in FRCs and thereby preserves myeloid cell composition in lymph nodes of naive mice. During localized lymphocytic choriomeningitis virus infection, IFNAR signaling precipitated profound phenotypic adaptation of all FRC subsets enhancing antigen presentation, chemokine-driven immune cell recruitment, and immune regulation. The IFNAR-dependent shift of all FRC subsets toward an immunostimulatory state reduced exhaustive CD8+ T cell activation. In sum, these results unveil intricate circuits underlying type I IFN sensing in lymph node FRCs that enable protective antiviral immunity.
