Abstract
Human papillomavirus type 8 (HPV8), a cutaneous genus beta HPV type, has co-carcinogenic potential at sun-exposed sites in patients suffering from the inherited skin disease epidermodysplasia verruciformis (EV). We had previously shown that Langerhans cells responsible for epithelial immunosurveillance were strongly reduced at infected sites and that the HPV8 E7 protein interferes with the CCAAT/enhancer-binding protein (C/EBP)β to suppress the Langerhans cell chemokine CCL20. At the same time, however, we observed that EV lesions are heavily infiltrated with inflammatory immune cells, which is similar to the situation in HPV8 E6 transgenic mice. To identify critical inflammatory factors, we used a broad multiplex approach and found that the monocyte attracting chemokine CCL2 was significantly and strongly induced by HPV8 E6 but not E7-expressing HaCaT cells, which were used as a model for UV-damaged skin keratinocytes. Conditioned media from HPV8 E6-expressing keratinocytes enhanced CCL2-receptor (CCR2)-dependent monocyte recruitment in vitro, and macrophages predominated in the stroma but were also detected in the epidermal compartment of EV lesions in vivo. CCL2 induction by HPV8 E6 was even stronger than stimulation with the proinflammatory cytokine TNF-α, and both HPV8 E6 and TNF-α resulted in substantial suppression of the transcription factor C/EBPα. Using RNAi-mediated knockdown and overexpression approaches, we demonstrated a mechanistic role of the recently identified C/EBPα/miR-203/p63 pathway for HPV8 E6-mediated CCL2 induction at protein and transcriptional levels. Epithelial co-expression of p63 and CCL2 was confirmed in HPV8 E6-expressing organotypic air-liquid interface cultures and in lesional EV epidermis in vivo. In summary, our data demonstrate that HPV8 oncoproteins actively deregulate epidermal immune homeostasis through modulation of C/EBP factor-dependent pathways. While HPV8 E7 suppresses immunosurveillance required for viral persistence, the present study provides evidence that E6 involves the stemness-promoting factor p63 to support an inflammatory microenvironment that may fuel carcinogenesis in EV lesions.

Abstract
Research groups must understand the needs and requirements of the public health service to be able to develop tools and strategies for supporting it in risk assessment and risk communication. The zoonotic research consortia RoBoPub, Q-GAPS, TBENAGER and ZooBoCo used the format of workshops to include the expertise of the public health service system in their work. We present the results of three workshops that were held with representatives of the German public health service as part of the annual congress of the Federal Association of Physicians of German Public Health Departments in 2018, 2019 and 2022. Each workshop, held in a world-café format, lasted 90 minutes and had its own thematic focus. In the first workshop, information on the goals, problems, solutions and expectations of the public health service from the research consortia concerning exposure to rodent-borne infections during their occupational and leisure-time activities as well as the use of risk maps was collected. In the second and third workshops, participants developed risk communication strategies based on scenarios of outbreaks and identifications of new risk areas. Each workshop had more than 20 participants, of which at least half worked for local public health authorities. Foremost, participants expected practical, target group-specific material for risk communication from the research groups. According to the experience of most participants, direct contact with the affected groups was essential for risk communication. To raise awareness of the situation and establish contact with the relevant target groups, social media can complement traditional media, especially for hard-to-reach groups. However, their use should be considered and planned carefully. The workshop format was appropriate for integrating the public health expertise in the research activities. The expectations of the public health service on material for risk communication could be translated into a guideline, a risk management plan and pathogen descriptions by the research groups. When integrating the expertise of the public health authorities in their work, research groups should consider how to reach a suitable panel of representatives and how to keep the workload for those at an acceptably low level.
