Diverse Igh repertoires require successful V(D)J recombination allowing B cell receptor expression and Ig secretion for humoral immune responses. Igh locus contraction has been implicated in generating spatial proximity between distal VH segments and t…
Plasmacytes, the effector arm of humoral immunity, produce sufficient amounts of specific antibodies to provide protection against infection or disease. The durability of this humoral protection depends on the generation of long-lived plasmacytes (LLPC…
The specificity of the immune response is critical to its biological function, yet the generality of immune recognition implies that antibody binding is multispecific or degenerate. The current work explores and quantifies this paradox through a system…
Regulatory T cells (Tregs) play a central role in immune homeostasis and the preservation of immunological self-tolerance. Treg activity depends on prolonged IL-2 receptor (IL-2R) signaling, and impairment or loss of this function has been linked to th…
After primary infection with varicella, varicella-zoster virus (VZV) establishes a latent state that precedes the clinical manifestation of herpes zoster. Growing evidence, however, indicates that latency is not merely quiescent but represents an activ…
BackgroundOperational tolerance, defined as stable liver graft function without immunosuppression, has been observed in select transplant recipients. While immune regulatory mechanisms have been implicated, the biological processes underlying tolerance…
Damage-associated molecular patterns (DAMPs) cause sterile auto- inflammation after a traumatic incident in human tissues via innate immunity. The auto-reactivity of natural killer T cells (NK-T cells) instigated by DAMP-activated exocytosis of dendrit…
Donor lymphocyte infusions (DLI) are a standard therapy following allogeneic hematopoietic cell transplantation (alloHCT) for preventing and treating leukemic relapse in high-risk patients, particularly those with myeloid malignancies such as acute mye…
IntroductionMetastasis formation poses a significant challenge to oncologists, as it severely limits the survival of colorectal cancer (CRC) patients. Recently, we demonstrated that CD44 promotes spontaneous distant metastasis in a CRC xenograft model….
Despite decades of progress, long-term outcomes in human organ transplantation remain challenging. Functional decline in transplanted organs has stagnated over the past two decades, with most patients requiring lifelong immunosuppression, therapies tha…
