Researchers at The University of Texas MD Anderson Cancer Center have developed a novel antibody-toxin conjugate (ATC) designed to stimulate immune-mediated eradication of tumors. According to preclinical results published today in Nature Cancer, the new approach combined the benefits of more well-known antibody-drug conjugates (ADCs) with those of immunotherapies.
The study, which examined the relationship between childhood exposure to trauma and vascular dysfunction among more than 400 Black adults in Atlanta ages 30 to 70, found that women who experienced childhood trauma had a worse vascular function, a preclinical marker of heart disease, while men had none. In addition, the findings indicated that women may be more vulnerable to a larger cumulative stress burden, eliciting varying physiological stress responses. Childhood trauma in women can cause arterial stiffness, or an impaired artery function of the cardiovascular system, contributing to major cardiac events, such as stroke and heart attack. It also contributes to heart disease, high blood pressure, and a malfunctioning small blood vessel system, which could damage tissues in the kidneys or brain.
A new peer-reviewed Perspective (review) article shows that many widely-used prescription medications unintentionally disrupt sterol biosynthesis, a critical process for brain development. This disruption could have significant implications for fetal brain development when medications are taken during pregnancy, particularly in individuals with genetic vulnerabilities affecting cholesterol production.
The brain may play a role in helping the ear regulate its sensitivity to sound and compensate for hearing loss by sending a signal to a structure in the inner ear known as the cochlea, according to a USC study that was just published in the Journal of Neuroscience. The discovery could help researchers develop treatments for tough-to-treat hearing disorders such as hyperacusis and tinnitus. The research team developed a new way to look at activity in the inner ear by adapting an imaging technique called optical coherence tomography (OCT), which is widely used to scan the retina for conditions like glaucoma and macular degeneration. The approach enabled them to capture real-time images of the cochlea in action in mice. The researchers found that in healthy mice, cochlear activity does not change over the short term. But in mice with genetic hearing loss, cochlear function increased, indicating that the brain was enhancing the cochlea’s sensitivity as a response to long-term hearing loss. The findings suggest that the brain can send signals to the remaining hair cells, essentially telling them to turn up the volume.
