An unusual case of cerebral toxoplasmosis in an HIV negative 11 year old child is reported. Central nervous system disease was assessed immunohistochemically in a brain biopsy specimen with TgP8--a specific monoclonal antibody against Toxoplasma gondii antigens--thus confirming IgG and IgM serology, technetium scan findings, and clinical data. In addition, an active parasitaemia was confirmed by DNA in situ hybridisation assay in white cells using an ABGTg4 probe. The child recovered after specific T gondii treatment. Follow up six months later showed that he was immunodeficient.

Preclinical and clinical studies have established that autoreactive immunoglobulin G (IgG) can drive neuropathic pain. We recently demonstrated that sciatic nerve chronic constriction injury (CCI) in male and female mice results in the production of pronociceptive IgG, which accumulates around the lumbar region, including within the dorsal root ganglia (DRG) and spinal cord, facilitating the development of neuropathic pain. These data raise the intriguing possibility that neuropathic pain may be alleviated by reducing the accumulation of IgG.

In this review, we present the efforts made so far in developing effective solutions to prevent infections caused by seven major respiratory pathogens: influenza virus, respiratory syncytial virus (RSV), the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), , (), , and . Advancements driven by the recent coronavirus disease 2019 (COVID-19) crisis have largely focused on viruses, but effective prophylactic solutions for bacterial pathogens are also needed, especially in light of the antimicrobial resistance (AMR) phenomenon. Here, we discuss various innovative key technologies that can help address this critical need, such as (a) the development of Lung-on-Chip ex vivo models to gain a better understanding of the pathogenesis process and the host-microbe interactions; (b) a more thorough investigation of the mechanisms behind mucosal immunity as the first line of defense against pathogens; (c) the identification of correlates of protection (CoPs) which, in conjunction with the Reverse Vaccinology 2.

Solution-based affinity assays are used for the selection and characterization of proteins that could be developed into therapeutic molecules. However, these assays have limitations for cell-surface proteins as in most cases their purification requires detergent solubilization and are unlikely to assume conformations in solution that resemble their native states in cell membranes. This report describes a novel electrochemiluminescence-based method, called MSD-CAT, for the affinity analysis of antibodies binding to cell-surface receptors.

Purpose: Dupilumab is a widely recommended treatment for moderate-to-severe atopic dermatitis (AD), with known ocular side effects but less frequent cutaneous reactions.
Material And Methods: This case report details a 52-year-old female patient with atopic dermatitis treated with dupilumab. After an initially successful treatment, the patient developed a rosacea-like dermatitis.
