Sex differences in vaccine-induced immunity in mice immunized with integrase-defective lentiviral vector delivering the SARS-CoV-2 Spike protein

IntroductionIntegrase-defective lentiviral vector (IDLV) delivering the optimized SARS-CoV-2 Spike protein induces strong and persistent immunity in mice. Here, we investigate potential sex-dependent differences by comparing female and male mice for ge…

Circulating IL-17A accumulation reflects effective target blockade with secukinumab in spondyloarthritis

ObjectivesTo investigate the dynamics of IL-17A levels in patients with spondyloarthritis (SpA) treated with secukinumab and to determine the relationship between circulating IL-17A forms and clinical response.MethodsWe analyzed serum IL-17A levels in …

Flat dose intravenous immunoglobulin primary infection prophylaxis in multiple myeloma patients on BCMA and GPRC5D bispecific antibody therapy: the Vanderbilt experience

Bispecific antibodies (BsAbs) can cause profound hypogammaglobulinemia. Conventional infection prophylaxis has utilized weight-based IVIG dosing. However, the use of flat IVIG dosing can significantly reduce IVIG utilization. We evaluated hypogammaglob…

Immunogenic insights and experimental validation of a multiepitope vaccine construct against Streptococcus pneumoniae

Streptococcus pneumoniae is a predominant cause of pneumonia, sinusitis, bacteremia, meningitis and otitis media especially in children and the elderly. The emergence of antibiotic resistance and shift towards non-vaccine serotypes has compromised the …

Absolute quantification of microRNA miR-875-5p in temporal artery biopsies and its biomarker potential for giant cell arteritis

ObjectivesTo perform absolute quantification of miR-875-5p expression in temporal artery biopsies (TABs) of patients with giant cell arteritis (GCA), associate miR-875-5p copy number with histological and clinical characteristics of patients with GCA, …

High throughput profiling of the B cell repertoire identifies systematic changes in the repertoire of individuals with Crohn’s disease

The B cell repertoire contains the recombined sequences that encode the entire antibody repertoire of an individual. The repertoire is made from three antigenic binding chains, namely the immunoglobulin heavy chain (IGH) and two immunoglobulin light ch…

Identification of a growth-inhibitory epitope in PfRipr5, a malaria vaccine candidate against Plasmodium falciparum

BackgroundThe Plasmodium falciparum Rh5-interacting protein (PfRipr) is a key component of the pentameric PTRAMP-CSS-PfRipr-CyRPA-RH5 (PCRCR) complex, which is essential for erythrocyte invasion. Antibodies against PfRipr can inhibit parasite growth, b…
