Cimeio Therapeutics Inc. has entered into a preclinical research collaboration with a researcher at the University of Pennsylvania (Penn) to research and evaluate a novel universal immunotherapy with potential to treat multiple blood and bone marrow cancers.

Researchers who follow their instincts and achieve slow results while trying to break barriers have little support. They replace it with persistence. This is the story of Katalin Karikó and Drew Weissman. What was once a dream in their minds was later a success.

Researchers who follow their instincts and achieve slow results while trying to break barriers have little support. They replace it with persistence. This is the story of Katalin Karikó and Drew Weissman. What was once a dream in their minds was later a success. Their work together for decades was essential to achieving mRNA vaccines, and their perseverance was rewarded today with the 2023 Nobel Prize in Medicine.

Lyme disease, caused by the bacteria Borrelia burgdorferi and transmitted by Ixodes ticks, is expanding in many countries, posing a significant global health concern. The outer surface protein A (OspA) of B. burgdorferi is currently the most promising target for vaccine development, primarily because of its broad conservation among different bacterial strains that cause the disease. In a recent publication, researchers from the University of Pennsylvania and collaborators proposed using a lipid nanoparticle-encapsulated nucleoside-modified mRNA (mRNA-LNP) platform, similar to that of clinical vaccines against SARS-CoV-2, to develop a vaccine against Lyme disease.

A new method of CAR T-cell immunotherapy developed by researchers at the University of Pennsylvania Perelman School of Medicine could serve as a treatment for most blood cancers. Until now, CAR T-based immunotherapy for hematological malignancies has targeted the antigens CD19 for B cells, CD7 for T cells, BCMA for myeloma, and CD33 for AML.

Verismo Therapeutics Inc. has entered into a licensing agreement with the University of Pennsylvania for worldwide exclusive rights for two newly discovered anti-CD19 binders, the result of a sponsored research agreement between the two parties.

Protein quality control research is “almost exclusively focused on heat shock proteins, which are ubiquitously present” up and down the evolutionary chain, Xiaolu Yang told BioWorld. But “for more sophisticated organisms, which we humans like to think we are, it’s a little odd that we still use the system that bacteria started with…. It seems like we should have something more. The TRIM system,” he added, “fills that gap.”

TRIMs or tripartite motif proteins are a group of quality control proteins that are found only in animals. One of their functions is to add ubiquitin tags to proteins, marking them for transport to the proteasome system. TRIMs are part of the innate antiviral defense system. But in the July 27, 2023, issue of Science, Yang, who is a professor of cancer biology in the Perelman School of Medicine at the University of Pennsylvania, and his colleagues reported that TRIM11 interacts with tau protein in multiple ways that were beneficial in preventing tauopathies.

α-Synucleinopathies constitute a set of neurological disorders including Parkinson’s disease (PD), dementia with Lewy bodies, multiple systems atrophy (MSA), and other rare disorders. The development of positron emission tomography (PET) tracers for imaging α-synuclein aggregates is essential for performing efficient and accurate diagnosis, tracking disease progression and monitoring efficacy of potential therapies.

Researchers have identified a druggable pocket on the phosphatase Wip1, which regulates the tumor suppressor TP53 as well as DNA damage repair proteins. The work, which was published in Frontiers in Molecular Biosciences on April 18, 2023, by researchers from the University of Pennsylvania, could lead to therapeutics targeting Wip1. And the computational deep learning methods used to identify the pocket are broadly useful for identifying what the authors call “cryptic” pockets.
