Proprietary transgenic mouse produces human form of FasL protein
MILAN, ITALY / ACCESSWIRE / May 4, 2023 / PinCell, a biotechnology company developing a first-in-class therapy for rare and debilitating autoimmune skin diseases, announced the successful completion of two independent in-vivo studies of its lead candidate (PC111) using a proprietary transgenic mouse model expressing the human form of the target protein (FasL). PinCell is a spin-off of the University of Modena and Reggio Emilia and was seed financed by Sofinnova Partners, a leading European venture capital firm based in Paris, London and Milan.

Using the proprietary transgenic mouse, PC111 inhibited the production of blisters by at least 80%, confirming previous studies in in-vitro and ex-vivo human models of pemphigus. PC111 was also shown to dose-dependently neutralize human FasL in another in-vivo setting involving the Concanavalin-A liver model, which induces an acute release of FasL into the blood.
"This is a great achievement for the company," said Dr. Antonino (Tony) Amato, Chief Executive Officer of PinCell. "It provides for the first time in-vivo proof of concept evidence of PC111 effect in a humanized disease setting."
"We feel a real sense of accomplishment," said Prof. Carlo Pincelli, founder and Chief Medical Officer at PinCell. "By developing a proprietary model, we have now shown that our antibody does indeed inhibit blister formation by binding specifically to the human target."
"What is more, the humanized FasL mouse model could prove to be a valuable tool to study the involvement of the Fas/FasL pathway in other diseases in which this pathway may play a key role in disease development and progression," Prof. Pincelli added.
About pemphigus
Pemphigus is a rare condition that affects about 300,000 patients worldwide. Conservatively, a treatment based on PC111 would be beneficial for over 30 percent of this population who are relapsing or refractory to first line treatments.
PinCell's therapy will be an alternative to steroids or immunosuppressants currently prescribed or under development. By acting downstream from the immune system, at the level of skin cells, PC111's innovative mode of action will contribute to the reduction or the avoidance of steroids/immunosuppressants, while showing a rapid onset of action.

TIS Helps Treasury Teams Navigate the Ongoing ISO 20022 Transition After the 2025 Banking Deadline10.12.2025 14:00:00 CET | Press release
BERLIN, DE / ACCESS Newswire / December 10, 2025 / Treasury Intelligence Solutions (TIS), a leading cloud-based platform for payments and cash management, is future-proofing organizations with specialized translation services in the wake of the recent November 2025 ISO 20022 deadline. A major turning point for the financial industry, SWIFT now requires banks to move their cross-border payment messages to ISO 20022. As a result, treasury teams are already seeing differences in how their banks send and receive payment information. Adapting to these changes will require a strategic approach to modernizing systems and processes. ISO 20022 replaces a patchwork of older standards with a single approach to structuring payment data. The new universal standard is designed to reduce confusion across markets, improve data quality, and support the level of transparency that regulators around the globe now expect. Moving to ISO 20022 payments takes time and strategic vision, especially when legacy
Majority of Australian Parents (65%) and U.S. Parents 58% Support Social Media Ban for Under 16s, but Kids Say It Risks Cutting Them Off from Key Connections9.12.2025 15:00:00 CET | Press release
New survey of 4,000 parents and children in the U.S. and Australia reveals sharp generational divides in support, fears, mental health expectations, and belief in government enforcement. WASHINGTON, DC / ACCESS Newswire / December 9, 2025 / The Family Online Safety Institute (FOSI) released new research today examining how parents and children in the United States and Australia view social media bans for anyone under 16. The findings reveal strong parental support for such bans, in contrast with widespread concern from children who fear losing friendships and support systems that exist primarily online. The research arrives as Australia implements a national under 16 social media ban, placing global attention on how the policy will affect youth and their families. FOSI's study surveyed 4,000 parents and children ages 10 to 17 to understand how both groups feel about restrictions, enforcement, and the broader impact of social media on daily life.
