Summary: This study aimed to understand adaptive immunity to SARS-CoV-2 by analyzing B cell epitopes and neutralizing activity in COVID-19 patients. Most patients showed neutralizing activity against SARS-CoV-2, with antibodies targeting the S protein or RBD, and a correlation between neutralizing antibody titer and IgG antibody titer. Analysis of patient serum revealed potential targets for vaccine development against SARS-CoV-2.

Summary: By fusing ACE2 derivatives and Spike-binding peptides to antibody Fc domains, entry inhibitors that can effectively neutralize SARS-CoV-2 variants have been developed. These inhibitors increase protein stability, neutralize free virus, and recruit effector functions to clear infected cells. Optimized ACE2 derivatives can neutralize all tested variants, while Spike-binding peptides show varying activities and resistance against certain variants. Both optimized ACE2 and tetrameric peptide inhibitors provide protection in a mouse model.

Summary: This study found that metalloproteases play an important role in the pathomechanism of COVID-19, promoting the fusion and syncytiation of SARS-CoV-2 spike protein. Inhibitors of metalloproteases may be beneficial in the treatment of COVID-19 patients.

Summary: The study demonstrates that SRT is an effective entry inhibitor against SARS-CoV-2 infection. It targets the S protein and is effective against various SARS-CoV-2 variants. Additionally, SRT can be used in combination with other antivirals to enhance its efficacy. In vivo experiments also show that SRT inhibits viral infection and alleviates inflammation and lung pathology.

Summary: COVID-19, caused by SARS-CoV-2, shares similarities with 2002 SARS-CoV and both use similar mechanisms to enter host cells. This study explores the potential of curcumin and its derivatives as inhibitors of the spike protein, which plays a crucial role in viral entry. However, further research is needed to investigate their efficacy.

Summary: The study found that Clec4g and CD209c lectins can bind to the Spike protein of SARS-CoV-2, interfering with the virus' attachment to cell surfaces and significantly reducing infections. This provides hope for pan-variant therapeutic interventions.

Summary: In this study, phenothiazine derivatives were identified as potential therapeutic drugs for the treatment of SARS-CoV-2 and future emerging human coronaviruses. These derivatives showed strong inhibition against pseudotyped SARS-CoV-2 and distinct variants of concern, including the Delta and Omicron variants. Mechanistic studies suggested that phenothiazines target the spike protein of SARS-CoV-2 and prevent proteolytic cleavage, thereby inhibiting viral infection.

Summary: This study developed a method for the expression and purification of SARS-CoV-2 spike protein from insect cells and investigated four recombinant protein constructs. The research found that insect cells could produce a large quantity of purified protein compared to mammalian cells. The study demonstrated the functionality and high purity of the produced proteins, showing their ability to bind to the ACE2 receptor.

Summary: Despite the availability of vaccines and therapeutics, continuous genetic alterations in the SARS-CoV-2 virus pose a persistent threat, especially to immunocompromised and elderly individuals. The virus enters host cells via the interaction of its spike protein (S protein) with different receptors on the cell surface, such as angiotensin-converting enzyme 2 (ACE2). This review discusses therapeutic approaches to block the interaction between SARS-CoV-2 and host cell receptors, as well as the identification of auxiliary entry receptors.

Summary: The study found that individuals previously infected with SARS-CoV-2 who were vaccinated with BTN162b2 showed the highest proportion of neutralizing antibodies one month after the second dose. However, women were more likely to lose neutralizing antibodies over time. A decreased T-cell response was observed in those with previous SARS-CoV-2 infection after the second BTN162b2 dose. Naive participants, on the other hand, exhibited an overall increased T-cell response. Additionally, a significant reduction in certain cytokine levels was found in both groups.

Summary: Frailty attracts research attention as it is a target for intervention to extend healthy life span. We propose that frailty has a fetal origin and is part of the spectrum of developmental origins of health and disease. Research is focused on the relationship between fetal programming, frailty-related disorders, and age-related diseases such as sarcopenia and dementia. A total life-course approach is necessary to combat frailty, requiring collaboration between physicians, gerontologists, obstetricians, and pediatricians.

Summary: This study evaluated the feasibility and efficacy of leucine supplementation in offsetting immune dysfunction in sarcopenia. The results showed that leucine supplementation not only improved muscle mass and restored mitochondrial respiratory function, but also reduced inflammation levels. These findings are important for the rational design and optimization of leucine supplementation in patients with sarcopenia and autoimmune diseases.
