J Immunol. 2026 Jun 7;215(6):vkag126. doi: 10.1093/jimmun/vkag126. ABSTRACT Germinal centers (GCs) are microanatomical structures in which antigen-specific B cells undergo proliferation, somatic hypermutation, and affinity-based competition to select high-affinity clones that differentiate into memory B cells and plasma cells (PCs). B cell progression through the GC is tightly regulated, and the molecular determinants that modulate … Read more

J Immunol. 2026 Jun 7;215(6):vkag147. doi: 10.1093/jimmun/vkag147. ABSTRACT Cell-to-cell communication is essential for maintaining homeostasis and coordinating complex biological processes in multicellular organisms. Classically, cells communicate using secreted peptides and metabolites and through cell contact-dependent signaling. Emerging studies over the past 20 years indicate that many cell types, including innate immune cells such as macrophages, … Read more

J Immunol. 2026 Jun 7;215(6):vkag118. doi: 10.1093/jimmun/vkag118. ABSTRACT Glycoprotein 130 (GP130) is an archetypal class I cytokine receptor that serves as a shared signalling subunit for a group of cytokines known as interleukin 6 (IL-6)-type cytokines. GP130 does not have an intrinsic kinase activity and relies on Janus kinases (JAK) 1, 2, or Tyrosine kinase … Read more

J Immunol. 2026 Jun 7;215(6):vkag144. doi: 10.1093/jimmun/vkag144. ABSTRACT Neuroblastoma (NB) is the most common extracranial solid tumor in children and remains a major therapeutic challenge in high-risk patients because of frequent recurrence and metastasis. γδT cells are a unique lymphocyte subset with potent antitumor activity and are widely distributed in NB tumors. However, the immunosuppressive … Read more

J Immunol. 2026 Jun 7;215(6):vkag120. doi: 10.1093/jimmun/vkag120. ABSTRACT Checkpoint inhibitors have transformed cancer treatment, yet predicting responses remains challenging. Mitochondrial quality decreases in tumor infiltrating lymphocytes and correlates with impaired antitumor immunity in animal models. Mitochondrial membrane potential (MMP) increases with T cell activation and may also indicate cellular dysfunction. Here, we assessed the MMP … Read more

J Immunol. 2026 Jun 7;215(6):vkag129. doi: 10.1093/jimmun/vkag129. ABSTRACT Despite an effective vaccine against the hepatitis B virus (HBV), there are about 250 million people living with chronic HBV (CHB) worldwide and one million deaths annually. Most children and about 5% of adults exposed to HBV will fail to clear the virus, developing a lifelong infection. … Read more

J Immunol. 2026 Jun 7;215(6):vkag146. doi: 10.1093/jimmun/vkag146. ABSTRACT In inflammatory tissue niches, macrophages encounter intense oxidative stress due to their own production of reactive oxygen and nitrogen species as part of antimicrobial defense. Our findings reveal that inflammatory macrophages deploy distinct, context-dependent redox-protective mechanisms to survive this self-inflicted stress, thereby avoiding ferroptotic cell death. Specifically, … Read more
