Toregem Biopharma, affiliated with Kyoto University, announced the clinical trials on Thursday and aims to bring the antibody drug to market by 2030. The company also hopes to eventually offer this treatment to individuals who lose teeth later in life.

The emergence of RNA viruses like SARS-CoV-2 underscores the urgent need for innovative strategies to combat infectious diseases. While RNA-targeting tools such as CRISPR/Cas13 hold promise, their effectiveness in the cytoplasm – where many RNA viruses replicate – has been limited. Now, scientists from Helmholtz Munich and the Technical University Munich (TUM) have introduced a groundbreaking solution: Cas13d-NCS. This molecular tool enables CRISPR RNA molecules within the nucleus to move to the cytoplasm, enhancing their efficacy in neutralizing RNA viruses.

Published in Cell Discovery, this advancement heralds a new era in precision medicine and proactive viral defense strategies, crucial for addressing ongoing and future global health threats posed by RNA viruses.

Dick McCarthy, an 82-year-old who had always been physically active, found himself sidelined by excruciating knee pain due to bone-on-bone arthritis. Traditional knee replacement surgery seemed daunting, given the lengthy rehabilitation involved. However, upon discovering the Regenerative Biologics Institute (RBI) in Vero Beach, McCarthy found hope in stem cell therapy.

McCarthy’s decision to undergo stem cell therapy was informed by a comprehensive consultation and evaluation with Jason Griffeth, M.S., the clinical director at RBI. The procedure, completed on a Saturday afternoon, was minimally invasive, allowing McCarthy to return to his daily routine immediately. Remarkably, within days, he was back on the pickleball court, experiencing restored comfort and mobility.

In the realm of cellular therapies, groundbreaking advancements have propelled treatments from theoretical concepts to clinical realities. Over the past decade, two pivotal technologies, chimeric antigen receptors (CAR) and genome editing, have spearheaded the development of revolutionary CAR T cell therapies for leukemia and lymphoma. These therapies, engineered through virus-mediated gene insertion ex vivo, empower T cells with synthetic receptors to recognize and eliminate tumor-specific antigens post-transplantation.

While genome editing, particularly utilizing clustered regularly interspaced short palindromic repeats (CRISPR), has shown promise in enhancing CAR T cell therapies, it also presents unique challenges. The permanent nature of DNA editing poses safety and efficacy concerns, prompting the need for innovative solutions. Addressing this need, bioengineer Lei (Stanley) Qi and physician immunologist Crystal Mackall at Stanford University have introduced multiplexed effector guide arrays (MEGA), an RNA editing tool designed to circumvent the limitations of DNA editing.

Attention deficit hyperactivity disorder (ADHD) affects millions worldwide, with profound impacts on both children and adults. Characterized by inattention, hyperactivity, and impulsivity, ADHD can significantly hinder academic and social functioning. While its genetic basis has long been acknowledged, identifying specific genes involved has remained a challenge. However, recent strides in research have illuminated a key player: the CDH2 gene.

Israeli scientists from Ben-Gurion University of the Negev and Soroka-University Medical Center have made a groundbreaking discovery, identifying CDH2 as a pivotal gene implicated in ADHD. CDH2 encodes N-cadherin, a protein essential for brain synapse activity and formation. Through meticulous investigation, researchers found that mutations in CDH2 disrupt synaptic activity, influencing molecular pathways and dopamine levels in brain regions associated with ADHD.

A recent study published in the Journal of Cell Biology has illuminated the crucial role played by the enzyme GCN5 in maintaining the expression of key structural proteins in skeletal muscle. These proteins are essential for fundamental functions such as breathing, posture, and locomotion. Led by an international team of researchers from the Faculty of Medicine at the University of Ottawa, this discovery holds promise for future therapeutics targeting muscle degeneration caused by factors like aging, cancer, and muscular dystrophy.

Over a span of approximately five years, Dr. Keir Menzies, a molecular biologist at the Faculty of Medicine, and his team conducted experiments involving a muscle-specific mouse “knockout” of GCN5. This enzyme, known for regulating various cellular processes, was disrupted to understand its impact on muscle health during physical stress, such as downhill treadmill running.
