Degrading modified proteins could treat Alzheimer’s, other ‘undruggable’ diseases

Certain diseases, including Alzheimer’s, are currently considered “undruggable” because traditional small molecule drugs can’t interfere with the proteins responsible for the illnesses. But a new technique that specifically targets and breaks apart certain proteins—rather than just interfering with them—may offer a pathway toward treatment.

Researchers develop simple, affordable HIV testing device

HIV is one of the world’s most serious public health challenges, and molecular detection plays a significant role in early diagnosis and antiretroviral therapy for HIV patients. The current “gold standard” of HIV testing requires expensive instruments and highly-trained personnel—leaving an unmet need for a rapid, sensitive, and affordable approach for molecular detection of HIV at the point of care.

Post-COVID syndrome visible in DNA, shows study

A reprogramming of which genes are active, and which are not, is visible in post-COVID sufferers. This is shown in a study from Linköping University, Sweden, on a small group of individuals. The researchers can see that genes associated with taste and smell, as well as cell metabolism, are affected in individuals with post-COVID syndrome. These findings may ultimately contribute to the development of new diagnostic tools for this and similar diseases.

Non-surgical treatment significantly reduces knee pain for adults, especially those 50 and older

Genicular nerve radiofrequency ablation is a minimally invasive treatment for knee pain due to osteoarthritis of the knee, and can significantly reduce pain, especially for adults who are 50 and older, according to new research to be presented at the Society of Interventional Radiology Annual Scientific Meeting in Phoenix, March 4–9. This is the first time a study has examined patient demographics, prior surgical history and other clinical characteristics that may predict the level of pain reduction after treatment.

Explaining why some patients may test positive for COVID-19 long after recovery

SARS-CoV-2, the virus that causes COVID-19, seems to have become a permanent presence in our lives. Research from Whitehead Institute Founding Member Rudolf Jaenisch’s lab reveals that this may be true on multiple levels. Jaenisch, postdoc Liguo Zhang, and colleagues have shown that when the virus infects people, it is capable of integrating parts of its genetic code into the human genome through a process called reverse transcription. This genomic integration is rare, but due to how many hundreds of millions of people have been infected, it has likely occurred many times.
