Neutrophil-avid nanocarrier uptake by STAT3 dominant-negative hyper-IgE syndrome patient neutrophils. Life Sci Alliance 2024; 7:e202402618.

Abstract
Recurrent infections are a hallmark of STAT3 dominant-negative hyper-IgE syndrome (STAT3 HIES), a rare immunodeficiency syndrome previously known as Jobs syndrome, along with elevated IgE levels and impaired neutrophil function. We have been developing nanoparticles with neutrophil trophism that home to the sites of infection via these first-responder leukocytes, named neutrophil-avid nanocarriers (NANs). Here, we demonstrate that human neutrophils can phagocytose nanogels (NGs), a type of NAN, with enhanced uptake after particle serum opsonization, comparing neutrophils from healthy individuals to those with STAT3 HIES, where both groups exhibit NG uptake; however, the patient group showed reduced phagocytosis efficiency with serum-opsonized NANs. Proteomic analysis of NG protein corona revealed complement components, particularly C3, as predominant in both groups. Difference between groups includes STAT3 HIES samples with higher neutrophil protein and lower acute-phase protein expression. The study suggests that despite neutrophil dysfunction in STAT3 HIES, NANs have potential for directed delivery of cargo therapeutics to improve neutrophil infection clearance.

Abstract
BACKGROUND Myhre syndrome is an exceedingly rare yet increasingly diagnosed genetic disorder arising from germline variants in the SMAD4 gene. Its core manifestation is the progression of stiffness and fibrosis across multiple organs. Individuals with Myhre syndrome exhibit a propensity for upper respiratory tract remodeling and infections. The molecular and cellular mechanisms underlying this phenotype remain unclear. OBJECTIVE We sought to investigate how SMAD4 pathogenic variants associated with Myhre syndrome affect SMAD4 protein levels, activation, and physiological functions in patient-derived nasal epithelial cells. METHODS Clinical observations were conducted on a cohort of 47 patients recruited at Massachusetts General Hospital from 2016 to 2023. Nasal epithelial basal cells were isolated and cultured from inferior turbinate brushings of healthy subjects (n = 8) and patients with Myhre syndrome (n = 3; SMAD4-Ile500Val, Arg496Cys, and Ile500Thr). Transcriptomic analysis and functional assays were performed to assess SMAD4 levels, transcriptional activity, and epithelial cell host defense functions, including cell proliferation, mucociliary differentiation, and bacterial elimination. RESULTS Clinical observations revealed a prevalent history of otitis media and sinusitis among most individuals with Myhre syndrome. Analyses of nasal epithelial cells indicated that SMAD4 mutations do not alter SMAD4 protein stability or upstream regulatory SMAD phosphorylation but enhance signaling transcriptional activity, supporting a gain-of-function mechanism, likely attributable to increased protein-protein interaction of the SMAD complex. Consequently, Myhre syndrome nasal basal cells exhibit reduced potential in cell proliferation and mucociliary differentiation. Furthermore, Myhre syndrome nasal epithelia are impaired in bacterial killing. CONCLUSIONS Compromised innate immunity originating from epithelial cells in Myhre syndrome may contribute to increased susceptibility to upper respiratory tract infections.

Abstract
Rationale Hyper IgE syndrome (STAT3-HIES), also known as Job's syndrome, is a rare immunodeficiency disease typically caused by dominant-negative STAT3 mutations. STAT3-HIES syndrome is characterized by chronic pulmonary infection and inflammation, suggesting impairment of pulmonary innate host defense. Objectives To identify airway epithelial host defense defects consequent to STAT3 mutations that, in addition to reported mutant STAT3 immunologic abnormalities, produce pulmonary infection. Methods STAT3-HIES sputum was evaluated for biochemical/biophysical properties. STAT3-HIES excised lungs were harvested for histology; bronchial brush samples were collected for RNA sequencing and in vitro culture. A STAT3-HIES-specific mutation (R382W), expressed by lentiviruses, and a STAT3 knockout, generated by CRISPR/Cas9, were maintained in normal human bronchial epithelia under basal or inflammatory (IL1β) conditions. Effects of STAT3 deficiency on transcriptomics, and epithelial ion channel, secretory, antimicrobial, and ciliary functions were assessed. Measurements and Main Results Mucus concentrations and viscoelasticity were increased in STAT3-HIES sputum. STAT3-HIES excised lungs exhibited mucus obstruction and elevated IL1β expression. STAT3 deficiency impaired CFTR-dependent fluid and mucin secretion, inhibited expression of antimicrobial peptides, cytokines, and chemokines, and acidified airway surface liquid at baseline and post-IL1β exposure in vitro. Notably, mutant STAT3 suppressed IL1R1 expression. STAT3 mutations also inhibited ciliogenesis in vivo and impaired mucociliary transport in vitro, a process mediated via HES6 suppression. Administration of a γ-secretase inhibitor increased HES6 expression and improved ciliogenesis in STAT3 R382W mutant cells. Conclusions STAT3 dysfunction leads to multi-component defects in airway epithelial innate defense, which, in conjunction with STAT3-HIES immune deficiency, contributes to chronic pulmonary infection.

Abstract
Staphylococcus aureus (S. aureus) is a significant human pathogen, in particular in patients with an underlying medical condition. It is equipped with a large variety of virulence factors enabling both colonization and invasive disease. The spectrum of manifestation is broad, ranging from superficial skin infections to life-threatening conditions like pneumonia and sepsis. As a major cause of healthcare-associated infections, there is a great need in understanding staphylococcal immunity and defense mechanisms. Patients with inborn errors of immunity (IEI) frequently present with pathological infection susceptibility, however, not all of them are prone to S. aureus infection. Thus, enhanced frequency or severity of S. aureus infections can serve as a clinical indicator of a specific underlying immunological impairment. In addition, the analysis of immunological functions in patients with susceptibility to S. aureus provides a unique opportunity of understanding the complex interplay between staphylococcal virulence and host immune predisposition. While the importance of quantitatively and qualitatively normal neutrophils is widely known, less awareness exists about the role of specific cytokines such as functional interleukin (IL)-6 signaling. This review categorizes well-known IEI in light of their susceptibility to S. aureus and discusses the relevant associated pathomechanisms. Understanding host-pathogen-interactions in S. aureus infections in susceptible individuals can pave the way for more effective management and preventive treatment options. Moreover, these insights might help to identify patients who should be screened for an underlying IEI. Ultimately, enhanced understanding of pathogenesis and immune responses in S. aureus infections may also be of relevance for the general population.

Abstract
Airway basal stem cells (BSCs) play a critical role in epithelial regeneration. Whether coronavirus disease (COVID-19) affects BSC function is unknown. Here, we derived BSC lines from patients with COVID-19 using tracheal aspirates (TAs) to circumvent the biosafety concerns of live-cell derivation. We show that BSCs derived from the TAs of control patients are bona fide bronchial BSCs. TA BSCs from patients with COVID-19 tested negative for severe acute respiratory syndrome coronavirus 2 RNA; however, these so-termed COVID-19-exposed BSCs in vitro resemble a predominant BSC subpopulation uniquely present in patients with COVID-19, manifested by a proinflammatory gene signature and STAT3 hyperactivation. Furthermore, the sustained STAT3 hyperactivation drives goblet cell differentiation of COVID-19-exposed BSCs in an air-liquid interface. Last, these phenotypes of COVID-19-exposed BSCs can be induced in control BSCs by cytokine cocktail pretreatment. Taken together, acute inflammation in COVID-19 exerts a long-term impact on mucociliary differentiation of BSCs.

Abstract
Autoimmune diseases arise from atypical immune responses that attack self-tissue epitopes, and their development is intricately connected to the disruption of the JAK-STAT signaling pathway, where SOCS proteins play crucial roles. Conditions such as autoimmune uveitis, psoriasis, lupus, and autoimmune encephalitis exhibit immune system dysfunctions associated with JAK-STAT signaling dysregulation. Emerging therapeutic strategies utilize JAK-STAT inhibitors and SOCS mimetics to modulate immune responses and alleviate autoimmune manifestations. Although more research and clinical studies are required to assess their effectiveness, safety profiles, and potential for personalized therapeutic approaches in autoimmune conditions, JAK-STAT inhibitors and SOCS mimetics show promise as potential treatment options. This review explores the action, effectiveness, safety profiles, and future prospects of JAK inhibitors and SOCS mimetics as therapeutic agents for psoriasis, autoimmune uveitis, systemic lupus erythematosus, and autoimmune encephalitis. The findings underscore the importance of investigating these targeted therapies to advance treatment options for individuals suffering from autoimmune diseases.

Abstract
Respiratory syncytial virus (RSV) can cause severe disease especially in infants; however, mechanisms of age-associated disease severity remain elusive. Here, employing human bronchial epithelium models generated from tracheal aspirate-derived basal stem cells of neonates and adults, we investigated whether age regulates RSV-epithelium interaction to determine disease severity. We show that following RSV infection, only neonatal epithelium model exhibited cytopathy and mucus hyperplasia, and neonatal epithelium had more robust viral spread and inflammatory responses than adult epithelium. Mechanistically, RSV-infected neonatal ciliated cells displayed age-related impairment of STAT3 activation, rendering susceptibility to apoptosis, which facilitated viral spread. In contrast, SARS-CoV-2 infection of ciliated cells had no effect on STAT3 activation and was not affected by age. Taken together, our findings identify an age-related and RSV-specific interaction with neonatal bronchial epithelium that critically contributes to severity of infection, and STAT3 activation offers a potential strategy to battle severe RSV disease in infants.
