by Dennis Thompson A new treatment appears to reduce food allergies in children and teens, according to interim clinical trial results. A lab-made monoclonal antibody called omalizumab (Xolair) significantly increased the amounts of common foods that children could eat without sparking an allergic reaction, the U.S. National Institute of Allergy and Infectious Diseases (NIAID) reported....

CAR T-Cell Therapy: A Cure for Systemic Autoimmune Diseases?
SAN DIEGO — CD19-directed chimeric antigen receptor (CAR) T-cell therapy, which has transformed the treatment landscape for B-cell malignancies, is now showing great promise in at least three distinct autoantibody-dependent autoimmune diseases. A single infusion of autologous CD19-directed CAR T-cell therapy led to persistent, drug-free remission in 15 patients with life-threatening systemic lupus erythematosus, idiopathic...

Structure of a central component of the human immune system revealed
by Ludwig Maximilian University of Munich The ASC speck is a central component of the NLRP3 inflammasome. Credit: iScience (2023). DOI: 10.1016/j.isci.2023.108382 A central component of the human immune system, the NLRP3 inflammasome plays an important role in fighting off infections. However, its chronic activation is also implicated in a variety of common diseases, such as...
Design modifications offer promise for safer and more effective mRNA therapeutics
University of Cambridge Researchers have discovered that misreading of therapeutic mRNAs by the cell’s decoding machinery can cause an unintended immune response in the body. They have identified the sequence within the mRNA that causes this to occur and found a way to prevent ‘off-target’ immune responses to enable the safer design of future mRNA...

Moderna’s mRNA-based RSV vaccine was effective at preventing RSV-associated lower respiratory tract disease in adults ages 60 and older, according to results of the randomized ConquerRSVopens in a...
WHO Recommends Monovalent XBB.1.5 Covid-19 Vaccines For Boosters
By CodeBlue | 14 December 2023 WHO recommends monovalent XBB.1.5 Covid-19 vaccines across different platforms against circulating variants. Malaysia’s MOH has yet to issue an updated Covid-19 vaccine advisory for 2024 or to announce if the monovalent XBB.1.5 vaccine will be procured. Vaccination of a senior male patient at a hospital.
