Biomarker Discovery
*Neurology
In this study of 143 early-stage MS patients, researchers identified key proteins in cerebrospinal fluid that predict disease progression. Lower levels of the protein NfL were notably predictive of stable disease two years later. Additionally, a set of 11 proteins accurately forecasted the severity of disability worsening, potentially guiding treatment strategies for MS.
*Infectious Disease
A recent study has identified a six-protein signature that can effectively differentiate between bacterial and viral infections in febrile children. This development holds promise for the creation of a rapid point-of-care diagnostic test, potentially improving the accuracy of diagnoses and the appropriate administration of antibiotics in pediatric care.
*Infectious Disease
This study tracking 181 COVID-19 survivors unveiled distinct protein patterns associated with long COVID recovery. Over a two-year timeline, it found that while most immune functions rebounded, neuron-related pathways remained suppressed. Eleven proteins crucial to lung recovery and smell disorders emerged as potential targets for tailored long COVID therapies.
Therapeutics
*Cancer-Antibodies
This study has introduced a novel antibody method for precise cancer therapy, utilizing dimeric IgA (dIgA) antibodies. These antibodies target and remove rogue proteins like the KRAS G12D mutation from cells, effectively stopping tumor progression. Early tests in mice indicate substantial tumor shrinkage with minimal adverse effects. This innovation promises more customized cancer treatments with reduced impact on healthy cells.
*Cancer-Kinase Inhibitors
Researchers profiled 1,183 compounds, cataloging 500,000 interactions in ProteomicsDB and identifying selective inhibitors for 72 kinases. Key findings include a potential SYK probe and insights into a CK2 inhibitor's selectivity, marking a valuable resource for chemical biology.
*Cancer-Combination Therapy
Utilizing IonStar proteomics, scientists quantified 5,514 proteins to understand how the FGFR inhibitor BGJ398 enhances gemcitabine's efficacy in treating pancreatic cancer. The study revealed significant metabolic and apoptotic pathway modifications, providing insights for overcoming drug resistance.
*Cancer-Novel Targets
Researchers have innovated 'structural surfaceomics,' a technique to identify cancer-specific surface protein conformations, typically undetectable through standard methods. Applied to acute myeloid leukemia (AML), the technique pinpointed a unique conformation of integrin β2 as a specific target. Using this target, they developed antibodies that enabled chimeric antigen receptor T cells to selectively eradicate AML cells with minimal impact on healthy cells. This breakthrough offers a promising avenue for identifying precise targets in cancer immunotherapy.
