In this paper studies are presented on specific cell-mediated immunity in humans and in laboratory and farm animals upon infection or immunization with bacteria of the genera Chlamydia and Chlamydophila. Such infection or immunization was demonstrated to affect the total number of T lymphocytes, their subpopulation profiles their cytotoxicity, and the activity of cytokines. The changes appeared already a few hours after infection or immunization and persisted for days or weeks.

Understanding the local-level variations in seasonality of human respiratory syncytial virus infection: a systematic analysis.

Background: While previous reports characterised global and regional variations in RSV seasonality, less is known about local variations in RSV seasonal characteristics. This study aimed to understand the local-level variations in RSV seasonality and to explore the role of geographical, meteorological, and socio-demographic factors in explaining these variations.
Methods: We conducted a systematic literature review to identify published studies reporting data on local-level RSV season onset, offset, or duration for at least two local sites.
Anti-inflammatory coupled anti-angiogenic airway stent effectively suppresses tracheal in-stents restenosis.

Excessive vascularization during tracheal in-stent restenosis (TISR) is a significant but frequently overlooked issue. We developed an anti-inflammatory coupled anti-angiogenic airway stent (PAGL) incorporating anlotinib hydrochloride and silver nanoparticles using advanced electrospinning technology. PAGL exhibited hydrophobic surface properties, exceptional mechanical strength, and appropriate drug-release kinetics.

Background: Enterovirus 71 (EV71) is one of the major causative agents of hand, foot, and mouth disease (HFMD), and can cause severe cerebral complications and even fatality in children younger than 5 years old. However, there is no specific medication for EV71 infection in clinical practice. Our previous studies had identified the 6-thioguanine (6-TG), an FDA-approved anticancer drug, as a potential antiviral agent, but its anti-EV71 activity is largely unknown, therefore, we aim to explore the antiviral effect of 6-TG on EV71.

Early investigation revealed a reduced risk of SARS-CoV-2 infection among social contacts of COVID-19 vaccinated individuals, referred to as indirect protection. However, indirect protection from SARS-CoV-2 infection-acquired immunity and its comparative strength and durability to vaccine-derived indirect protection in the current epidemiologic context of high levels of vaccination, prior infection, and novel variants are not well characterized. Here, we show that both vaccine-derived and infection-acquired immunity independently yield indirect protection to close social contacts with key differences in their strength and waning.

Passion fruit woodiness disease (PWD), caused by cowpea aphid-borne mosaic virus (CABMV), severely damages leaves and fruits, compromising passion fruit production. The dynamics of this infection in Passiflora spp. are still poorly understood.
