    Abstract Clinical observations and mechanistic studies in dedicator of cytokinesis 8 (DOCK8)-deficient patients and mice have revealed multiple mechanisms that could contribute to their unusually prevalent and severe allergic disease manifestations. Physical interactions of DOCK8 with STAT3 in B cells and T cells may contribute to increased IgE isotype switching or defective immune synapse formation that decreases T-cell receptor signal strength.

    Abstract Maturation of the adaptive immune response is typically thought to improve outcome to virus infections. However, long-standing observations of natural infections with old viruses such as Epstein-Barr virus and newer observations of emerging viruses such as severe acute respiratory syndrome coronavirus 2 responsible for COVID-19 suggest that immune immaturity may be beneficial for outcome. Mechanistic studies and studies of patients with inborn errors of immunity have revealed that immune dysregulation reflecting inappropriate antibody and T-cell responses plays a crucial role in causing bystander inflammation and more severe disease. Further evidence supports a role for innate immunity in normally regulating adaptive immune responses. Thus, changes in immune responses that normally occur with age may help explain an apparent protective role of immune immaturity during virus infections.

    Abstract Infection with SARS-CoV-2 results in clinical outcomes ranging from silent or benign infection in most individuals to critical pneumonia and death in a few. Genetic studies in patients have established that critical cases can result from inborn errors of TLR3- or TLR7-dependent type I interferon immunity, or from preexisting autoantibodies neutralizing primarily IFN-α and/or IFN-ω. These findings are consistent with virological studies showing that multiple SARS-CoV-2 proteins interfere with pathways of induction of, or response to, type I interferons. They are also congruent with cellular studies and mouse models that found that type I interferons can limit SARS-CoV-2 replication in vitro and in vivo, while their absence or diminution unleashes viral growth. Collectively, these findings point to insufficient type I interferon during the first days of infection as a general mechanism underlying critical COVID-19 pneumonia, with implications for treatment and directions for future research.

    Abstract Human rhinoviruses (RV) are a frequent cause of respiratory tract infections with substantial morbidity and mortality in some patients. Nevertheless, the genetic basis of susceptibility to RV in humans has been relatively understudied. Experimental infections of mice and in vitro infections of human cells have indicated that various pathogen recognition receptors (TLRs, RIG-I, and MDA5) regulate innate immune responses to RV. However, deficiency of MDA5 is the only one among these so far uncovered that confers RV susceptibility in humans. Other work has shown increased RV susceptibility in patients with a polymorphism in CDHR3 that encodes the cellular receptor for RV-C entry. Here, we provide a comprehensive review of the genetic determinants of human RV susceptibility in the context of what is known about RV biology.

    Abstract SARS-CoV-2 infection displays immense inter-individual clinical variability, ranging from silent infection to lethal disease. The role of human genetics in determining clinical response to the virus remains unclear. Studies of outliers-individuals remaining uninfected despite viral exposure and healthy young patients with life-threatening disease-present a unique opportunity to reveal human genetic determinants of infection and disease.

    Abstract Purpose of review: Studying primary immunodeficiencies (PIDs) provides insights into human antiviral immunity in the natural infectious environment. This review describes new PIDs with genetic defects that impair innate antiviral responses.
    Recent findings: New genetic defects in the interferon (IFN) signaling pathway include IFNAR1 deficiency, which causes uncontrolled infections with measles-mumps-rubella or yellow fever vaccines, and possibly also cytomegalovirus (CMV); and IRF9 deficiency, which results in influenza virus susceptibility. Genetic defects in several pattern recognition receptors include MDA5 deficiency, which impairs viral RNA sensing and confers human rhinovirus susceptibility; RNA polymerase III haploinsufficiency, which impairs sensing of A:T-rich virus DNA and confers VZV susceptibility; and TLR3 deficiency, which causes HSV-1 encephalitis (HSE) or influenza virus pneumonitis. Defects in RNA metabolism, such as that caused by Debranching enzyme 1 deficiency, can cause virus meningoencephalitis. Finally, defects in host restriction factors for virus replication, such as in CIB1 deficiency, contribute to uncontrolled β-HPV infections.
    Summary: Several new PIDs highlight the role of type I/III IFN signaling pathway, virus sensors, and host virus restriction factors in human antiviral immunity.
