The essential event in picornavirus entry is the delivery of the RNA genome to the cytoplasm of a target cell, where replication occurs. In the past several years progress has been made in understanding the structural changes in the virion important for uncoating and RNA release. In addition, for several viruses the endocytic mechanisms responsible for

Virus entry is initiated by recognition by receptors present on the surface of host cells. Receptors can be major mediators of virus tropism, and in many cases receptor interactions occur in an apparently programmed series of events utilizing multiple receptors.

Epstein-Barr virus primarily, though not exclusively, infects B cells and epithelial cells. Many of the virus and cell proteins that are involved in entry into these two cell types in vitro have been identified, and their roles in attachment and fusion are being explored.

Entry Diversion: Entry Barriers to Divert Submarket Entry
Academy of Management Proceedings, 2018Deterring entrants has long been a key concern for incumbents, yet scholars struggle to create a theoretical foundation that is consistent with the empirical patterns.

Entry Policy and Entry Subsidies
Review of International Economics, 1999Optimal entry policy is considered in markets served by both domestic and foreign firms. Compared with the prior entry literature, introducing foreign producers as market participants reduces incentives for entry deterrence and enhances incentives for entry subsidization. Incentives are changed because entry produces “terms‐of‐trade” gains. The optimal

Many recent studies of keyboard entry are summarized with particular emphasis on performance data and fundamental questions about the design of keyboards. The role of auditory and visual feedback and physiological measurements are reviewed. Typical speed and error rates are given for several types of situations and operators.

Recent research indicates that when entrants incur set-up costs there is a tendency for oligopolistic industries to support too many firms. This is because incumbents accommodate entrants by reducing their output and making entry profitable beyond the point where it is socially efficient.

Epstein-Barr virus chiefly infects B cells and epithelial cells but is capable of infecting other cell types in the human host. Host cell entry is a complex process mediated by several viral glycoproteins that define tropism and mediate membrane fusion.

Entry and Entry Deterrence in Penetrable Markets
Economica, 1988This paper presents a game theoretic model of entry. A potential entrant into a given market is postulated to be a currently produci ng firm, whose product is a substitute on the production side for the good being sold in the market. An entrant is capable of switching pr oduction between markets faster than firms in general can adjust thei r total ...
