The viral capsid structure is a protein shell that encases and protects the viral genome, playing a crucial role in the infection process by facilitating the attachment and entry of the virus into host cells. Its design can vary from simple helical and icosahedral forms to more complex structures, influencing the virus's stability, infectivity, and immune evasion strategies.

Viral Capsid Structure

viral capsid structure

A protein shell, often referred to as a capsid, is a protective layer that encases the genetic material of viruses, facilitating their stability and transmission. It is composed of protein subunits that self-assemble into a highly ordered structure, playing a crucial role in the infectivity and life cycle of the virus.

A viral genome is the complete genetic material of a virus, which can be composed of either DNA or RNA and varies significantly in size and structure among different types of viruses. Understanding the viral genome is crucial for deciphering viral replication mechanisms, evolution, and for developing antiviral strategies and vaccines.

infection process

When a virus wants to make you sick, it first has to stick to your cells and then get inside them. This is how it starts to make you feel unwell, by taking over your cells and making more of itself.

attachment and entry

Host cells are living cells in which a virus or other microorganism can replicate and produce progeny. They provide the necessary machinery and environment for the pathogen's replication, often at the expense of the host's normal cellular functions.

Complex structures are intricate arrangements of interconnected components that exhibit emergent properties not present in individual elements. They are studied across various disciplines to understand how these systems function, adapt, and evolve over time.

Infectivity refers to the ability of a pathogen to establish an infection in a host. It is a critical factor in understanding how diseases spread and is influenced by both the pathogen's characteristics and the host's susceptibility.
