Unveiling an Immunological Mystery: Deciphering the Durability Divide in Vaccine-Elicited Antibody Responses.

Achieving durable antibody-mediated protection remains critical in vaccine develop-ment, particularly for viral diseases like COVID-19 and HIV. We discuss factors influencing an-tibody durability, highlighting the role of long-lived plasma cells (LLPCs) in the bone marrow, which are essential for sustained antibody production over many years. The frequencies and prop-erties of bone marrow LLPC are critical determinants of the broad spectrum of antibody durability for different vaccines.

Rapid, sensitive, and species-independent detection of Crimean Congo hemorrhagic fever virus nucleoprotein and GP38 antibodies.

Background: Crimean-Congo hemorrhagic fever virus (CCHFV), a zoonotic agent in the Nairoviridae family (genus Orthonairovirus), is a high-priority pathogen. CCHFV infection causes Crimean-Congo hemorrhagic fever (CCHF), a human disease with case fatality rates of up to 40%. Serological surveillance of CCHFV in animals and humans is crucial for ecological studies and public health.

A comprehensive engineering strategy improves potency and manufacturability of a near pan-neutralizing antibody against HIV.

Anti-HIV envelope broadly neutralizing antibodies (bnAbs) are alternatives to conventional antiretrovirals with the potential to prevent and treat infection, reduce latent reservoirs, and/or mediate a functional cure. Clinical trials with "first-generation" bnAbs used alone or in combination show promising antiviral effects but also highlight that additional engineering of "enhanced" antibodies will be required for optimal clinical utility, while preserving or enhancing Current Good Manufacturing Practices (cGMP) manufacturing capability. Here, we report the engineering of an anti-CD4-binding site (CD4bs) bnAb, N49P9.

Survival and prognostic factors in rhino-orbito-cerebral mucormycosis: A 3-year cohort study.

Mucormycosis, a severe fungal infection, has exhibited a concerning increase in recent years, particularly during the COVID-19 outbreak. This three-year cohort study aims to investigate an overview of the epidemiology, clinical and radiographic signs, treatment, and prognosis of Rhino-Orbito-Cerebral Mucormycosis (ROCM). This prospective cohort study was conducted from 2019 to 2022 at Khalili Hospital in Shiraz, Iran.

Penile human papillomavirus prevalence in circumcised sexual minority men with and without HIV.

Objective: Understanding the burden of penile human papillomavirus (HPV) among high-risk groups is essential to inform tailored prevention strategies to reduce HPV-related morbidity. We estimated the prevalence of penile HPV and its association with HIV among circumcised sexual minority men (SMM).

Design: A cross-sectional study from a community-based cohort of SMM with and without HIV in Nigeria.
