The low seroprevalent human adenovirus type 26 (HAdV26)-based vaccine vector was the first adenovirus-based vector to receive marketing authorization from European Commission. HAdV26-based vaccine vectors induce durable humoral and cellular immune responses and, as such, represent a highly valuable tool for fighting infectious diseases. Despite wel...

... Adenoviral DNA or RNA transcripts have the potential to stimulate intracellular Toll-like receptors (TLRs) 3 There are two main pathways through which this reactivation may occur. Firstly, both human IL-6 and the KSHV-encoded homolog vIL-6 have been shown to reactivate KSHV [4]. Studies have demonstrated that adenovirus vector infection of human epithelial cells induces the expression of pro-inflammatory cytokines, particularly IL-6. ...
In this case report, we present a distinctive occurrence of classic Kaposi sarcoma (KS) in an individual of Latin origin, emerging seven days following the administration of the third dose of the ChAdOx1 nCoV-19 (AstraZeneca) vaccine. The progression of KS continued over two months, culminating in the development of a tumor. Given the absence of prior reports on KS development post-COVID-19 vaccination, the primary aim of this report is to explore the potential relationship between the ChAdOx1 nCoV-19 vaccine, reactivation of Kaposi sarcoma-associated herpes virus, and the subsequent onset of KS.
Inflammatory reaction and neovascularization are crucial physiological processes that occur during postoperative wound healing. However, excessive inflammatory response and uncontrolled angiogenesis lead to scar formation, which severely limits the success rate of glaucoma filtration surgery. Peptide hydrogels were well-established to possess good biocompatibility, inherent biodegradability, extracellular matrix analog property, and high drug loading efficiency. Herein, we examined the potential of Arg-Gly-Asp (RGD) peptide hydrogel to inhibit inflammation and angiogenesis in vitro experiments. RGD peptide hydrogel exhibited significant inhibitory effects on the inflammatory response by ELISA and western blot and considerable prohibitive effects on neovascularization via inhibiting the proliferation and migration of vascular endothelial cells. In this study, we found a novel biomaterial, RGD peptide hydrogel, which has a certain anti-cell proliferation and anti-scarring effect in vitro experiments.

Pilomatrixoma, or calcifying epithelioma of Malherbe, is a benign tumor with differentiation toward the hair matrix cells and is one of childhood's most common epithelial tumors. Bullous pilomatrixoma has an extremely low incidence of occurrence, usually appears in the upper extremities, and is frequently associated with trauma. We report the case of a bullous pilomatrixoma in a patient with a rapid-growing neoformation one month after receiving a coronavirus disease 2019 (COVID-19) vaccine in his left upper arm, and we discuss whether the bullous appearance is part of the biology of the tumor or a secondary anetoderma.
