Humoral immunity

Humoral immunity refers to antibody-mediated immune responses. Antibodies are produced by plasma cells and protect the host from infection in three main ways: by binding to pathogens to inhibit their toxic effects or infectivity (neutralization), by coating pathogens and facilitating their uptake and killing by phagocytes (opsonization) and by activating the complement cascade.

    Orthobunyaviruses (OBVs) cause severe disease in humans and farm animals, but the molecular basis for infection is not fully understood. Here, the authors present crystal structures of free and antibody-bound OBV envelope glycoproteins and show that their domains enable efficient immunization in a mouse model.

    Stemness is crucial for the maintenance of long-term T cell memory. Gattinoni and colleagues demonstrate that the transcription factor c-Myb is essential for the establishment of a stemness program in the CD8+ T cell memory compartment.

    Cross-protective responses across all strains of influenza virus (IAV, IBV and ICV) are a key goal of universal vaccines against influenza. Kedzierska and colleagues identify cytotoxic T cells present in blood and lungs of healthy people that are directed against all strains of influenza virus.

    Signalling of the B cell receptor (BCR) is pivotal for survival and activation of naïve B cells. Here the authors show, using super-resolution microscopy techniques, that BCRs exist primarily as monomers and dimers in resting B cells, and oligomerize only on stimulation, thereby implicating a function of BCR clustering patterns on B cell biology.

    T cells express specific T cell receptors (TCR) to recognise antigens and initiate adaptive immune responses. Here the authors show, in a mouse model of autoimmune encephalomyelitis, that memory-like CD4 T cells expressing unrelated TCR can also infiltrate the spinal cord and contribute to autoimmunity.

    A multivalent vaccine that presents diverse influenza virus subtype H1 hemagglutinins on its surface induces broadly neutralizing antibodies in an animal model by displaying conserved epitopes at higher density than strain-specific epitopes.

    The study of B cell biology is a mature field, but highlights from the past year remind us that there are still many exciting and unexpected things to be discovered in terms of B cell responses to antigen, germinal centres and plasma cells.

    The generation of an HIV vaccine remains the holy grail for eliminating HIV infection worldwide. Major advances in 2018 centred on sequential multi-immunogen strategies that are designed to induce broadly neutralizing antibodies, identifying new targets and defining new approaches to immunogen evaluation.
