Deciphering the HLA-E immunopeptidome with mass spectrometry: an opportunity for universal mRNA vaccines and T-cell-directed immunotherapies

Frontiers in Immunology
Advances in immunotherapy rely on targeting novel cell surface antigens, including therapeutically relevant peptide fragments presented by HLA molecules, collectively known as the actionable immunopeptidome.

Mycobacterium tuberculosis peptides presented by HLA-E molecules are targets for human CD8 T-cells with cytotoxic as well as regulatory activity.

PLoS Pathogens, 2010
Tuberculosis (TB) is an escalating global health problem and improved vaccines against TB are urgently needed. HLA-E restricted responses may be of interest for vaccine development since HLA-E displays very limited polymorphism (only 2 coding variants ...

Optimization of B Cell Responses in Human Immune System Mice Through Organoid Based Screening

Advanced Science, EarlyView.
Human immune system (HIS) mice show limited B cell responses to immunization. Using HIS mouse spleen organoids, this study identifies cytokine combinations and innate immune signals that drive human B cell expansion, differentiation, and class‐switch. Applying these signals in vivo through temporal separation enables antigen‐specific IgG responses and ...

HLA Class Ia and Ib Polyreactive Anti-HLA-E IgG2a Monoclonal Antibodies (TFL-006 and TFL-007) Suppress Anti-HLA IgG Production by CD19+ B Cells and Proliferation of CD4+ T Cells While Upregulating Tregs

Journal of Immunology Research, 2017
The anti-HLA-E IgG2a mAbs, TFL-006 and TFL-007, reacted with all HLA-I antigens, similar to the therapeutic preparations of IVIg. Indeed, IVIg lost its HLA reactivity, when its HLA-E reactivity was adsorbed out.

Viral sequence determines HLA-E-restricted T cell recognition of hepatitis B surface antigen

Nature Communications
AbstractThe non-polymorphic HLA-E molecule offers opportunities for new universal immunotherapeutic approaches to chronic infectious diseases. Chronic Hepatitis B virus (HBV) infection is driven in part by T cell dysfunction due to elevated levels of the HBV envelope (Env) protein hepatitis B surface antigen (HBsAg). Here we report the characterization

Contributions of vitamin D response elements and HLA promoters to multiple sclerosis risk [PDF]

, 2012
Objective: The identification of a vitamin D-responsive (VDRE) motif within the HLA-DRB1*15:01 promoter region provides an attractive explanation for the combined effects of HLA-DR inheritance and vitamin D exposure on multiple sclerosis (MS) risk.

Triple‐Negative Breast Cancer Cells Utilize IL8 and CXCL1 to Suppress NK Cells’ Function and Facilitate Cancer Metastasis

Advanced Science, EarlyView.
Triple‐negative breast cancer (TNBC) cells evade natural killer (NK) cell immunity by secreting IL8 and CXCL1. These chemokines suppress NK cells’ function via CXCR1/2 and enhance cancer cells’ survival through PD‐L1 upregulation and BCL‐2 anti‐apoptotic signaling.
