Matthew Wiebe, a virologist at the University of Nebraska-Lincoln, has received a $2.2 million grant from the National Institutes of Health to study how poxviruses hijack cellular circuitry during infection. Wiebe aims to understand how poxviruses manipulate cell signaling pathways and how and why they have evolved to mirror human genes and proteins. He believes studying this mimicry can better understand human cellular biology and potential weaknesses in our immune system and identify strategies for fighting viruses and other diseases.
Poxviruses are fertile ground for studying mimicry as they closely resemble human cellular genes. Wiebe plans to conduct proteomics and interactome studies on the vaccinia virus to explore how it uses the duplicated structures and which cellular signaling pathways they’re involved in. He is particularly interested in the signaling of kinases and pseudokinases and the role of proteins on the frontline of the virus-host battle, such as BAF and HUSH.
Revealing the mechanics of these pathways may be relevant to understanding the development of other diseases, such as cancer, infertility, autoimmunity, and neurodegeneration. Wiebe hopes his research might open the door to new strategies for tackling these problems.
While Wiebe embraces the unknown in his research, he also recognizes the importance of shedding light on viral mimicry and its impact on immune function. His work highlights the significance of understanding the complex interplay between poxviruses and human cells and how this knowledge can lead to disease prevention and treatment breakthroughs. The pressure on banks today is very different from what it was during the financial crisis of 2008. Social media, online banking, and shifts in regulation have all contributed to a banking landscape that is more vulnerable to fast-spreading rumors and quick withdrawals of funds. This is “the first bank crisis of the Twitter generation,” according to Paul Donovan, the chief economist at UBS Global Wealth Management.
One of the most significant changes in the banking sector since 2008 is the rise of social media. Rumors can spread exponentially faster than ever, leading to a loss of reputation and trust in banks. Mobile banking has also changed how people interact with banks, with online transactions being much more common than in-person transactions. This combination of quick information dissemination and access to funds can make banks more vulnerable to runs and panics.
However, some positive changes in the banking sector make a repeat of the 2008 financial crisis less likely. For example, banks are now required to hold more capital as a buffer, and regulators are more attuned to the risks and dangers that banks face. Bank leverage ratios are also lower, indicating that risk in the banking system today is significantly less than over the past few decades.
While individual players can still face difficulties, the banking sector is more resilient than in 2008. However, trust and confidence in the system are still crucial, as a lack of trust played a big part in the recent European banking turmoil. Trust is the most critical capital for banks, and if it is lost, anything can happen.
The pressure on banks today differs significantly from during the 2008 financial crisis. While social media has made it easier for rumors to spread and funds to be withdrawn quickly, regulation and oversight have also improved, making the banking sector more resilient. Trust and confidence in the system are still crucial; however, vigilance is required to prevent banks’ failures and a loss of faith.
