Enhancement of T. lymphocyte functions by Fc fragments of immunoglobulin. II. Augmentation of the cell-mediated lympholysis response occurs through an Lyt-1+2- helper T cell.

Journal of Immunology, 1981
Fc fragments derived from papain digestion of human IgG have the capacity to augment specific T cell-mediated cytolytic responses. The addition of Fc fragments to cultures containing nylon wool-purified effector and irradiated stimulator cells results in

Comparing Antibody Interfaces to Inform Rational Design of New Antibody Formats

Frontiers in Molecular Biosciences, 2022
As the current biotherapeutic market is dominated by antibodies, the design of different antibody formats, like bispecific antibodies and other new formats, represent a key component in advancing antibody therapy.

Function‐driven design of a surrogate interleukin‐2 receptor ligand

FEBS Letters, EarlyView.
Interleukin (IL)‐2 signaling can be achieved and precisely fine‐tuned through the affinity, distance, and orientation of the heterodimeric receptors with their ligands. We designed a biased IL‐2 surrogate ligand that selectively promotes effector T and natural killer cell activation and differentiation. Interleukin (IL) receptors play a pivotal role in

An immune evasion mechanism with IgG4 playing an essential role in cancer and implication for immunotherapy

Journal for ImmunoTherapy of Cancer, 2020
Background Recent impressive advances in cancer immunotherapy have been largely derived from cellular immunity. The role of humoral immunity in carcinogenesis has been less understood.

Intein‐based modular chimeric antigen receptor platform for specific CD19/CD20 co‐targeting

Molecular Oncology, EarlyView.
CARtein is a modular CAR platform that uses split inteins to splice antigen‐recognition modules onto a universal signaling backbone, enabling precise, scarless assembly without re‐engineering signaling domains. Deployed here against CD19 and CD20 in B‐cell malignancies, the design supports flexible multi‐antigen targeting to boost T‐cell activation and

Engineering tandem VHHs to target different epitopes to enhance antibody‐dependent cell‐mediated cytotoxicity

FEBS Open Bio, EarlyView.
Tandem VHH targeting distinct EGFR epitopes were engineered into a monovalent bispecific antibody (7D12‐EGA1‐Fc) with more potent ADCC without increasing affinity to EGFR. Structural modeling of 7D12‐EGA1‐Fc showed cross‐linking of separate EGFR domains to enhance CD16a engagement on NK cells.

Gamma-globulin Inhibits Superantigen-induced Lymphocyte Proliferation and Cytokine Production

Allergology International, 2007
Background: High-dose pooled human immunoglobulin (PHIG) treatment is sometimes effective in superantigen related inflammatory diseases, such as toxic shock syndrome and Kawasaki disease.
