The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection can result in a new disease called long-COVID or post-acute COVID-19 syndrome (PACS). Individuals diagnosed with PACS experience persistent cardiac manifestations, such as palpitations,...
The S1 protein activates human CFs by priming NLRP3 inflammasomes through NF-κB signaling in an ACE2-dependent way.
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can infect the human placenta. In this study, the authors from Italy performed immunohistochemical analyses to determine whether SARS-CoV-2 alters markers involved in vascular damage and the autophagic...

These results demonstrated that nAChR subtypes interact with the neurotoxin-like region of the SARS-CoV-2, confirming that the α7 nAChR is a target for the SARS-CoV-2.
This study found, for the first time in children, that levels of IgG4 antibodies specific for S1 and RBD significantly increased one year after the second vaccination compared to baseline.
SARS-CoV-2 enters human erythrocytes, but in a low percentage of cells (10.9%) compared to SARS-CoV-2 permissive cell lines. The presence of SARS-CoV-2 in blood culture did not affect the survival or growth rate of the malaria parasite.
This case report describes a fully vaccinated woman positive for a non-Omicron variant of SARS-CoV-2 who experienced a spontaneous internal carotid dissection. A dissection was treated successfully with a flow-diverter stent.

The BNT162b2 mRNA COVID-19 vaccine directly affects the activity of ovarian granulosa cells, which is a unique, independent mechanism for vaccine-related menstrual abnormalities.
Histamine receptor H1 acts as an independent receptor for SARS-CoV-2. Additionally, H1 directly interacts with ACE2, synergistically enhancing ACE2-dependent viral entry.
This study analyzes recent research on natural products derived from plants, honey, and marine sponges with properties against the SARS-CoV-2, as well as several potential mechanisms of their action,

The Japanese National Institute of Infectious Diseases reports a rise in the number of patients with toxic shock syndrome in Japan.
This retrospective study of 4,520 pediatric patients infected with the Omicron variant of SARS-CoV-2 demonstrated that acute necrotizing encephalopathy and pneumonia with comorbidities were the main causes of death.
A rare case of COVID-19-associated unilateral encephalitis, characterized by severe involvement of the left cerebral hemisphere.
The observed changes in Glu/Gln balance, total N-acetyl-compound levels and MI provided evidence of neuronal injury or loss as ell as persistent neuroinflammation and glial dysfunction in the brains of post-COVID individuals, and are consistent with findings associated with brain damage in other neurodegenerative diseases, such as neuroHIV.
On December 8th, 2023, the World Health Organization announced that Zambia had reported its largest anthrax outbreak for a decade.
Seven antigenic sites of SARS-CoV-2 spike RBD showed molecular similarities with 54 antigenic determinants found in fifteen pathogen microorganisms, including bacteria, parasites and viruses.
