Tyrosine phosphorylation is one of the most important posttranslational modifications in bacteria, linked to regulating growth, migration, virulence, secondary metabolites, biofilm formation, and capsule production. Only two tyrosine kinases (yccC (etk) and wzc) have been identified in . The investigation by similarity has not revealed any novel BY-kinases so far, most probably due to their sequence and structural variability.

Objectives: RA is an autoimmune disease characterized by chronic inflammation and joint destruction. Biologics are crucial to achieving treat-to-target goals in patients with RA. The global spread and continuous variation of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) necessitate the monitoring of variant-specific humoral responses post-vaccination.

The continuous mutation of SARS-CoV-2 highlights the need for rapid, cost-effective, and high-throughput detection methods. To better analyze the antibody levels against SARS-CoV-2 and its variants in vaccinated or infected subjects, we developed a multiplex detection named Barcode Bead Fluorescence (BBF) assay. These barcode beads were magnetic, characterized by 2-dimensional edges, highly multiplexed, and could be decrypted with visible light.

Article Synopsis
  • Kawasaki disease (KD) is an acute systemic vasculitis mainly affecting children under 5, with potential links to genetic factors and infections.
  • A study examined the immune responses of 90 KD patients compared to 69 non-KD controls after COVID-19 infection and varying doses of the BNT162b2 vaccine.
  • Results showed KD patients had lower binding antibodies but higher neutralizing antibodies to certain SARS-CoV-2 variants after receiving one vaccine dose, indicating they may develop a similar immune response to non-KD individuals.

In November 2022, 68% of the population received at least one dose of COVID-19 vaccines. Owing to the ongoing mutations, especially for the variants of concern (VOCs), it is important to monitor the humoral immune responses after different vaccination strategies. In this study, we developed a SARS-CoV-2 variant protein microarray that contained the spike proteins from the VOCs, e.

The disease progression of COVID-19 varies from mild to severe, even death. However, the link between COVID-19 severities and humoral immune specificities is not clear. Here, we developed a multiplexed spike variant protein microarray (SVPM) and utilized it for quantifying neutralizing activity, drug screening, and profiling humoral immunity.

SARS-CoV-2 is quickly evolving from wild-type to many variants and spreading around the globe. Since many people have been vaccinated with various types of vaccines, it is crucial to develop a high throughput platform for measuring the antibody responses and surrogate neutralizing activities against multiple SARS-CoV-2 variants. To meet this need, the present study developed a SARS-CoV-2 variant (CoVariant) array which consists of the extracellular domain of spike variants, e.

Coronavirus is an enveloped RNA virus that causes mild to severe respiratory diseases in humans, including HKU1-CoV, 229E-CoV, NL63-CoV, OC43-CoV, SARS-CoV, MERS-CoV, and SARS-CoV-2. Due to the outbreak of SARS-CoV-2, it is important to identify the patients and investigate their immune responses. Protein microarray is one of the best platforms to profile the antibodies in the blood because of its fast, multiplexed, and sensitive nature.

Being the green gold of the future, microalgae and cyanobacteria have recently attracted considerable interest worldwide, for their metabolites such as lipids, protein, pigments, and bioactive compounds have immense potential for sustainable energy and pharmaceutical production capabilities. In the last decades, the efforts attended to enhance the usage of microalgae and cyanobacteria by genetic manipulation, synthetic and metabolic engineering. However, the development of photoautotrophic cell factories have rarely compared to the heterotrophic counterparts due to limited tools, bioinformatics, and multi-omics database.
