Long-lived Plasma Cells Are Contained Within the CD19−CD38hiCD138+ Subset in Human Bone Marrow

open access: yesImmunity, 2015
Antibody responses to viral infections are sustained for decades by long-lived plasma cells (LLPCs). However, LLPCs have yet to be characterized in humans. Here we used CD19, CD38, and CD138 to identify four PC subsets in human bone marrow (BM). We found

Targeting antigen to CD19 on B cells efficiently activates T cells [PDF]

open access: yesInternational Immunology, 2005
CD19 is a B cell-surface molecule that participates as an important regulatory signaling complex for antigen bound at the surface by Ig. Triggering of CD19 through its linkage with CD21 amplifies signals transduced through the Src family kinases and modulates B cell differentiation in response to antigen.

The CD19/CD21 Complex Functions to Prolong B Cell Antigen Receptor Signaling from Lipid Rafts [PDF]

open access: yes, 2001
The CD19/CD21 complex functions to significantly enhance B cell antigen receptor (BCR) signaling in response to complement-tagged antigens. Recent studies showed that following antigen binding the BCR translocates into plasma membrane lipid rafts that ...

PROTAC‐Engineered Protein/DNA Nanoantigen is a Potent Booster for Dendritic Cell Vaccines in Cancer Immunotherapy

open access: yesAdvanced Science, EarlyView.
A PROTAC‐functionalized protein/DNA‐integrated nanoantigen platform is developed to enhance dendritic cell vaccine potency. By combining a VHL‐recruiting peptide‐modified antigen with a sustained expression plasmid within CaCO3 nanoparticles, this system amplifies cross‐presentation, promotes DC maturation, and elicits robust Th1 and CTL responses ...

Table_1_Probiotic Lactobacillus rhamnosus GG Induces Alterations in Ileal Microbiota With Associated CD3-CD19-T-bet+IFNγ+/- Cell Subset Homeostasis in Pigs Challenged With Salmonella enterica Serovar 4,[5],12:i:-.DOC

open access: yes, 2019
Salmonella enterica serovar 4,[5],12:i:- (S. 4,[5],12:i:-) is an emerging foodborne pathogen causing salmonellosis in humans and animals. Probiotic Lactobacillus rhamnosus GG (LGG) is an effective strategy for controlling enteric infections through ...

Serodiagnosis of Echinococcus spp. infection: explorative selection of diagnostic antigens by peptide microarray [PDF]

open access: yes, 2010
BACKGROUND: Production of native antigens for serodiagnosis of helminthic infections is laborious and hampered by batch-to-batch variation. For serodiagnosis of echinococcosis, especially cystic disease, most screening tests rely on crude or purified ...

Canonical Antibodies Adopt Distinct Binding Modes to Recognize Viral Glycan Shields

open access: yesAdvanced Science, EarlyView.
Canonical Y‐shaped antibodies recognize viral glycan shields through adaptive Fab assembly states shaped by glycan organization and somatic hypermutation. Structural analyses ofbroadly neutralizing antibodies VRC35 and VRC36 across glycoproteins of HIV‐1, influenza, SARS‐CoV‐2, and Lassa viruses reveal distinct Fab assembly states, spanning monovalent,

Development of specific nanobodies (VHH) for CD19 immuno-targeting of human B-lymphocytes [PDF]

open access: yesIranian Journal of Basic Medical Sciences, 2018
Objective(s): CD19 is a transmembrane glycoprotein of immunoglobulin superfamily. In order to treat lymphoma, monoclonal antibodies (mAb) can target different antigens, including CD19, CD20 and CD22 on the surface of B-cells.

A Drug‐Gated, Modular STAb‐T Immunotherapy With External Control

open access: yesAdvanced Science, EarlyView.
Engineered STAb‐TON cells act as programmable living factories that continuously secrete inactive antibody modules, which assemble extracellularly into a functional T cell engager only upon small‐molecule administration. This externally controlled platform enables reversible, on‐demand regulation of antitumor immunity, establishing a new paradigm for ...

Preclinical development of three novel CARs targeting CD79b for the treatment of non-Hodgkin’s lymphoma and characterization of the loss of the target antigen

open access: yesJournal for ImmunoTherapy of Cancer
Background Infusion of T cells modified with a chimeric antigen receptor (CAR) targeting CD19 has achieved exceptional responses in patients with non-Hodgkin’s lymphoma (NHL), which led to the approval of CAR targeting CD19 (CART19) (Axi-cel and Liso-cel)
