Hand, foot and mouth disease (HFMD) has been widespread in the world, and caused fever, rashes and other clinical symptoms of children, and sometimes inducing respiratory failure, brainstem encephalitis, and other complications, even death. The disease is mainly caused by enterovirus 71 (EV-A71) and coxsackievirus 16 (CV-A16). Since 2013, the proportion of HFMD cases caused by other enteroriruses has gradually increased, causing severe and even fatal cases. Read More

Electronic address:

RNA-remodeling proteins, including RNA helicases and chaperones, play vital roles in the remodeling of structured RNAs. During viral replication, viruses require RNA-remodeling proteins to facilitate proper folding and/or re-folding the viral RNA elements. Coxsackieviruses B3 (CVB3) and Coxsackieviruses B5 (CVB5), belonging to the genus Enterovirus in the family Picornaviridae, have been reported to cause various infectious diseases such as hand-foot-and-mouth disease, aseptic meningitis, and viral myocarditis.

Chemokine PF4 Inhibits EV71 and CA16 Infections at the Entry Stage.

J Virol 2022 May 17:e0043522. Epub 2022 May 17.

Center of Infectious Diseases and Pathogen Biology, Institute of Virology and AIDS Research, Key Laboratory of Organ Regeneration and Transplantation of The Ministry of Education, The First Hospital of Jilin University, Changchun, China.

Platelet factor 4 (PF4) or the CXC chemokine CXCL4 is the most abundant protein within the α-granules of platelets. Previous studies found that PF4 regulates infections of several viruses, including HIV-1, H1N1, hepatitis C virus (HCV), and dengue virus. Here, we show that PF4 is an inhibitor of enterovirus A71 (EV71) and coxsackievirus A16 (CA16) infections. Read More

Aseptic Meningitis in Oral Medicine: Exploring the Key Elements for a Challenging Diagnosis: A Review of the Literature and Two Case Reports.

Int J Environ Res Public Health 2022 03 25;19(7). Epub 2022 Mar 25.

Oral Medicine Unit, Department of Neurosciences, Reproductive and Oral Sciences, "Federico II" University of Naples, 80131 Naples, Italy.

Aseptic meningitis (AM) is a potentially severe and life-threatening disease characterized by meningeal inflammation, usually with mononuclear pleocytosis. It represents a challenging and controversial issue in medicine for multiple etiologies, classification, and difficult diagnosis in the face of nonspecific sets of signs and symptoms. In the area of interest of oral medicine, in specific clusters of patients, even if rare, the occurrence of aseptic meningitis can pose a diagnostic and management dilemma in the following potential etiologies: (i) systemic diseases with oral and meningeal involvement, which include Behçet's disease and Sjögren syndrome; (ii) drug-induced aseptic meningitis; (iii) aseptic viral meningitis, mostly related to herpes simplex virus infection and hand, foot, and mouth disease, caused by enteroviruses.
