Credit: The Wistar Institute PHILADELPHIA -- (Jan. 12, 2021) -- Scientists at The Wistar Institute have created an advanced humanized immune system mouse model that allows them to examine resistance to immune checkpoint blockade therapies in melanoma. It has revealed a central role for mast cells. These findings were published today in the journal Nature Communications. Checkpoint inhibitors revolutionized therapeutic options for advanced melanoma. However, only a fraction of patients respond to this treatment and some relapse due to reemergence of therapy-resistant lesions. "To better unde...

Credit: The Wistar Institute PHILADELPHIA -- (Dec. 23, 2020) -- Wistar Institute scientists have discovered a new class of compounds that uniquely combine direct antibiotic killing of pan drug-resistant bacterial pathogens with a simultaneous rapid immune response for combatting antimicrobial resistance (AMR). These finding were published today in Nature. The World Health Organization (WHO) has declared AMR as one of the top 10 global public health threats against humanity. It is estimated that by 2050, antibiotic-resistant infections could claim 10 million lives each year and impose a cumul...
