Antibody response to Plasmodium vivax in the context of Epstein-Barr virus (EBV) co-infection: A 14-year follow-up study in the Amazon rainforest. by Luiz F F Guimarães, Bárbara A Rodrigues, Michelle H F Dias, Matheus G Barcelos, Maria F A Nascimento, Sâmick L Moreira-Nascimento, Sofia L Afonso, Barbara G S Abreu, Jaap M Middeldorp, Francis B Ntumngia, John H Adams, Camila Fabbri, Stefanie Lopes, Cor J F Fernandes, Flora S Kano, Luzia H Carvalho

“…The experimental approach focused on monitoring antibodies to the major blood-stage P. vivax vaccine candidate, the Duffy binding protein region II (DBPII-Sal1), including a novel engineered DBPII-based vaccine targeting conserved epitopes (DEKnull-2). In parallel, the status of EBV infection was determined over time by the detection of circulating EBV DNA (EBV-DNAemia) and EBV-specific antibodies to lytic (VCAp18) or latent (EBNA1) antigens. …”

Negative Association of Gulf War Illness Symptomatology with Predicted Binding Affinity of Anthrax Vaccine Antigen to Human Leukocyte (HLA) Class II Molecules by Lisa M. James, Apostolos P. Georgopoulos

“…Method: Here, we tested this hypothesis by determining the association between severity of GWI symptoms in 458 GW veterans and the overall strength of the binding affinity of the PA epitopes to the specific six Human Leukocyte Antigen (HLA) Class II alleles carried by each individual (two of each of the HLA-II genes: DPB1, DQB1, DRB1), responsible for initiating the process of antibody production in otherwise immunocompetent individuals, estimated in silico. …”

Shed antigen-induced blocking effect on CAR-T cells targeting Glypican-3 in Hepatocellular Carcinoma by Wei Gao, Tong Ding, Beicheng Sun, Nan Li, Fang Gao, Meng Jia, Mitchell Ho, Na Li, Luan Sun, Zhanhui Gao, Lei Ao, Sujuan Ma, Peihua Lu, Shaochang Jia

“…Therefore, it would be worth investigating the potential influence of antigen shedding in anti-GPC3 CAR-T therapy for HCC.Methods In this study, we constructed two types of CAR-T cells targeting distinct epitopes of GPC3 to examine how sGPC3 influences the activation and cytotoxicity of CAR-T cells in vitro and in vivo by introducing sGPC3 positive patient serum or recombinant sGPC3 proteins into HCC cells or by using sGPC3-overexpressing HCC cell lines.Results Both humanized YP7 CAR-T cells and 32A9 CAR-T cells showed GPC3-specific antitumor functions in vitro and in vivo. …”

TCR-engaging scaffolds selectively expand antigen-specific T-cells with a favorable phenotype for adoptive cell therapy by Marco Donia, Özcan Met, Julie Westerlin Kjeldsen, Sine Reker Hadrup, Inge Marie Svane, Arianna Draghi, Anders Handrup Kverneland, Christina Heeke, Siri Amanda Tvingsholm, Marcus Svensson Frej, Vibeke Mindahl Rafa, Ulla Kring Hansen, Maria Ormhøj, Alexander Tyron, Agnete W P Jensen, Mohammad Kadivar, Amalie Kai Bentzen, Kamilla K Munk, Gitte N Aasbjerg, Jeppe S H Ternander, Tripti Tamhane, Christian Schmess, Samuel A. Funt, Søren Nyboe Jakobsen

“…To generate an ‘off-the-shelf’ multitargeting Ag-scaffold product of relevance to patients with metastatic melanoma, we identified the 30 most frequently recognized shared HLA-A0201-restricted melanoma epitopes in a cohort of 87 patients. By combining these in an Ag-scaffold product, we were able to expand tumor-specific T-cells from 60–70% of patients with melanoma, yielding a multitargeted T-cell product with up to 25% specific and phenotypically and functionally improved T cells.Conclusions Taken together, the Ag-scaffold represents a promising new technology for selective expansion of antigen-specific CD8+ T cells directly from blood, yielding a highly specific and functionally enhanced T-cell product for ACT.…”

Immunogenetics of longevity and its association with human endogenous retrovirus K by Lisa M. James, Lisa M. James, Lisa M. James, Apostolos P. Georgopoulos, Apostolos P. Georgopoulos, Apostolos P. Georgopoulos, Apostolos P. Georgopoulos

“…IntroductionThe human immune system is equipped to neutralize and eliminate viruses and other foreign antigens via binding of human leukocyte antigen (HLA) molecules with foreign antigen epitopes and presenting them to T cells. HLA is highly polymorphic, resulting in subtle differences in the binding groove that influence foreign antigen binding and elimination. …”

Pre-existing IgG antibodies to HCoVs NL63 and OC43 Spike increased during the pandemic and after COVID-19 vaccination by Zahra Hasan, Kiran Iqbal Masood, Marc Veldhoen, Shama Qaiser, Marta Alenquer, Mishgan Akhtar, Sadaf Balouch, Junaid Iqbal, Yaqub Wassan, Shahneel Hussain, Khalid Feroz, Sajid Muhammad, Atif Habib, Akbar Kanji, Erum Khan, Afsar Ali Mian, Rabia Hussain, Maria Joao Amorim, Zulfiqar A. Bhutta

“…IgG antibodies to Spike SARS-CoV-2 were positively correlated with HCoV-NL63 in HC 2021, indicating recognition of shared conserved epitopes. IgG antibody levels increased during the pandemic; 2.7-fold to HCoV-NL63 and 1.9-fold to HCoV-OC43.SinoVac and BNT162b2 vaccine induced an increase in IgG antibodies to Spike SARS-CoV-2 as well as HCoV-NL63 and HCoV-OC43.Our data show that antibodies to spike protein of endemic coronaviruses were present in the prepandemic population. …”

Therapeutic depletion of CCR8+ tumor-infiltrating regulatory T cells elicits antitumor immunity and synergizes with anti-PD-1 therapy by James Dooley, Bart Neyns, Elizabeth Allen, Frank Tacke, Louis Boon, Damya Laoui, Julia Katharina Schwarze, Helena Van Damme, Bruno Dombrecht, Máté Kiss, Heleen Roose, Eva Van Overmeire, Daliya Kancheva, Liesbet Martens, Aleksandar Murgaski, Pauline Madeleine Rachel Bardet, Gillian Blancke, Maude Jans, Evangelia Bolli, Maria Solange Martins, Yvon Elkrim, Kiavash Movahedi, Niels Vandamme, Sebahat Ocak, Isabelle Scheyltjens, Lars Vereecke, Frank Aboubakar Nana, Pascal Merchiers, Jo Agnes Van Ginderachter

“…We generated two CCR8-specific nanobodies (Nbs) that recognize distinct epitopes on the CCR8 extracellular domain. These Nbs were formulated as tetravalent Nb-Fc fusion proteins for optimal CCR8 binding and blocking, containing either an antibody-dependent cell-mediated cytotoxicity (ADCC)-deficient or an ADCC-prone Fc region. …”
