BACKGROUND Vaccination against influenza is recommended for patients with common variable immunodeficiency (CVID), although humoral immune responses in these patients are impaired and the evidence of effective T-cell responses in CVID is not well established. OBJECTIVE To determine plasmablast and T-cellular vaccination responses against influenza in patients with CVID METHODS CVID patients and healthy controls were vaccinated with the quadrivalent vaccine Influsplit Tetra 2018/2019. Before and one week after vaccination plasmablasts and circulating ICOS expressing T follicular helper cells were measured to determine positive vaccine responses in these patients. Additionally, antigen-specific T cells were determined by their upregulation of CD25 and OX40 after in vitro re-stimulation with the vaccine. RESULTS The majority of healthy controls but only one CVID patient mounted a positive humoral immune response, measured by an increase of plasmablasts one week after vaccination. In contrast, the majority of CVID patients showed an increase of ICOS+ TFH cells and/or an increase of antigen-specific CD25+OX40+ T cells one week after vaccination demonstrating a positive T-cellular immune response. CONCLUSION Despite the remaining challenge of accurately assessing the complexity of T-cell responses the recommendation of vaccinating CVID patients against influenza is reasonable. Lysphosphatidic acid (LPA) is a major natural bioactive lipid mediator whose biological functions affect multiple organs. These include bone as demonstrated by global Lpar1-knockout mice (Lpar1-/-) which present a bone growth defect. LPA acts on all bone cells including osteoblasts,
