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. …”
