All-Round Manipulation of the Actin Cytoskeleton by HIV

While significant progress has been made in terms of human immunodeficiency virus (HIV) therapy, treatment does not represent a cure and remains inaccessible to many people living with HIV. Continued mechanistic research into the viral life cycle and its intersection with many aspects of cellular biology are not only fundamental in the continued fight against HIV, but also provide many key observations of the workings of our immune system. Decades of HIV research have testified to the integral role of the actin cytoskeleton in both establishing and spreading the infection. Here, we review how the virus uses different strategies to manipulate cellular actin networks and increase the efficiency of various stages of its life cycle. While some HIV proteins seem able to bind to actin filaments directly, subversion of the cytoskeleton occurs indirectly by exploiting the power of actin regulatory proteins, which are corrupted at multiple levels. Furthermore, this manipulation is not restricted to a discrete class of proteins, but rather extends throughout all layers of the cytoskeleton. We discuss prominent examples of actin regulators that are exploited, neutralized or hijacked by the virus, and address how their coordinated deregulation can lead to changes in cellular behavior that promote viral spreading.

East-Meets-West: Mergers and Acquisitions challenges and opportunities in and out of Asia

Mergers and Acquisitions (M&As) have long been a strategically important corporate strategy for growth and global expansion. Research on M&As in Asian contexts is linked to the relevant countries’ phenomenal business growth, economic transformation, and institutional development. To consolidate and synthesise the existing body of knowledge related to the ‘East-Meets-West’ notion, this paper will present an examination of the characteristics of M&As both in and out of Asia from an international perspective, with a geographical focus on China, Japan, and South Korea. We investigated the influencing factors related to the distinctiveness and commonalities of M&As in and out of Asia. Our findings suggest that the divergence in Asian M&As may be driven by industrial characteristics and national environments, while their convergence may be due to human aspects. Our study contributes to the divergence and convergence debate in the context of in and out of Asia M&As in relation to the East-Meets-West concept.
