Medically reviewed by Steffini Stalos, DO Key Takeaways CD4 T helper cells help the body fight infections by signaling other ...

Understanding the interplay between T cells and B cells is pivotal to delineating both protective immunity and the pathogenesis of autoimmune diseases. Central to this dynamic are specialised CD4⁺ T ...

CD4 tests are strongly recommended as the preferred method to identify advanced HIV disease among people living with HIV, the ...

This study, led by Dr. Panpan Jiang and collaborators at Tongji Medical College, explores the critical role of the Dedicator of Cytokinesis 8 (DOCK8) gene in the differentiation of helper T cells, ...

Interleukin-9 (IL-9) is a multifunctional cytokine that plays a critical role in regulating immune responses, allergic inflammation and host defence mechanisms. T helper 9 (TH9) cells, a specialised ...

Previously thought to be a bug in the system, new research shows CD4 T cells could be the key to maintaining an age-appropriate immune system BEER-SHEVA, Israel, October 29, 2025 – Ben-Gurion ...

In a person living with HIV, proviruses—strands of HIV DNA—are typically integrated into the T cell genome and become a ...

Scientists analyzing human and mouse pancreatic lymph nodes (PLNs) and spleens have identified a distinct subset of CD4 memory helper T cells associated with type 1 diabetes (T1D). Reported by ...

During infections, the immune system needs to distinguish foreign molecules from invading bacteria and viruses from molecules that are made by cells of the body. If it can’t, the immune system can ...

Study reveals that moderate fever temperatures (39°C) improve metabolism, proliferation, and effector function of CD4 T cells while reducing regulatory T cell suppression. Study: Subset-specific ...

The brain and spinal cord were once thought to enjoy immune privilege, meaning they were believed to be largely insulated from immune activity elsewhere in the body. In recent years, however, ...

Researchers at Johns Hopkins Medicine have reported evidence that standard chemotherapeutic drugs may selectively suppress ...
