Background/aim: The most frequently altered epigenetic modifier in head and neck squamous carcinoma (HNSC) is the histone methyltransferase KMT2D. KMT2D catalyzes methylation of histone H3K4 resulting in open chromatin and the activation of target genes. Tumor-associated macrophages (TAMs) promote cancer growth by causing T lymphocyte exhaustion.

This is a crucial gap in our understanding because it prevents us from discovering how genetic mutations and environmental risks that alter synaptic function cause prefrontal network to fail in schizophrenia. To address that question, we developed a recurrent spiking network model of prefrontal local circuits that can explain the link between NMDAR synaptic and 0-lag spike synchrony deficits we recently observed in a pharmacological monkey model of prefrontal network failure in schizophrenia.

However, the systemic administration of IL12 has been accompanied by considerable toxicity, prompting interest in researching alternatives to drive preferential IL12 bioactivity in the tumor. Here, we have generated XTX301, a tumor-activated IL12 linked to the human Fc protein via a protease cleavable linker that is pharmacologically inactivated by an IL12 receptor subunit beta 2 masking domain.
