A 14-kDa gene-specific probe of vaccinia virus Western Reserve (WR) hybridized to homologous sequences in the genomes of the orthopox virus species cowpox, camelpox, mousepox, and monkeypox virus. The corresponding genes were mapped and sequenced. Homologies of more than 95% were found when compared to the 14-kDa gene of vaccinia virus WR. However, point mutations which led to alterations in the amino acid sequences were mainly located between residues 26 and 40. By use of synthetic peptides, this part of the 14-kDa fusion protein could be identified as the binding site for four different neutralizing monoclonal antibodies.

Background: Vertical HIV-1 transmission despite antiretroviral therapy may be mitigated by use of long-acting, broadly neutralizing, monoclonal antibodies (bNAb) such as VRC07523LS. The present study was designed to determine the safety and pharmacokinetics of VRC07523LS.
Methods: VRC07523LS, 80 mg/dose, was administered subcutaneously after birth to non-breastfed (Cohort 1; N=11, enrolled in USA) and breastfed (Cohort 2; N=11, enrolled in South Africa and Zimbabwe) infants exposed to HIV-1.

In the tumour microenvironment, IL-1α promotes neoangiogenesis, matrix remodelling, tumour proliferation, chemoresistance, and metastases. Highly expressed in human colorectal cancers, IL-1α is associated with poor prognosis. XB2001, a fully human monoclonal antibody neutralizing IL-1α, was evaluated for safety and preliminary efficacy with trifluridine/tipiracil (FTD/TPI) and bevacizumab in metastatic colorectal cancer patients previously treated with oxaliplatin- and irinotecan-based chemotherapies.

Objectives: We previously reported that CCL17 gene-deficient mice are protected from developing pain-like behaviour and exhibit less disease in destabilization of medial meniscus (DMM)-induced OA, as well as in high-fat diet (HFD)-exacerbated DMM-induced OA. Here, we explored if therapeutic neutralization of CCL17, using increasing doses of a neutralizing monoclonal antibody (mAb), would lead to a dose-dependent benefit in these two models.
Design: DMM-induced OA was initiated in male mice either fed with a control diet (7% fat) or 8 weeks of a 60% HFD, followed by therapeutic intraperitoneal administration (i.

Background: Sotrovimab is a neutralising monoclonal antibody (nMAB) currently available to treat extremely clinically vulnerable COVID-19 patients in England. Trials have shown it to have mild to moderate side effects, however, evidence regarding its safety in real-world settings remains insufficient.
Methods: Descriptive and multivariable logistic regression analyses were conducted to evaluate uptake, and a self-controlled case series analysis performed to measure the risk of hospital admission (hospitalisation) associated with 49 pre-specified suspected adverse outcomes in the period 2-28 days post-Sotrovimab treatment among eligible patients treated between December 11, 2021 and May 24, 2022.

The pathogenesis of thoracic aortic aneurysm (TAA) in Marfan syndrome (MFS) is generally attributed to vascular smooth muscle cell (VSMC) pathologies. However, the role of immune cell-mediated inflammation remains elusive. Single-cell RNA sequencing identified a subset of CX3CR1+ macrophages mainly located in the intima in the aortic roots and ascending aortas of Fbn1C1041G/+ mice, further validated in MFS patients.
