The main benefit of cell-based vaccines is the ability to rapidly produce vaccine supplies during an impending pandemic.Cell-based antigen production offer a faster and more stable production of vaccines compared to embryonic chicken eggs, which produce 1-2 vaccine doses per chicken egg. [8]
A subunit vaccine is a vaccine that contains purified parts of the pathogen that are antigenic, or necessary to elicit a protective immune response. [1] [2] Subunit vaccine can be made from dissembled viral particles in cell culture or recombinant DNA expression, [3] in which case it is a recombinant subunit vaccine.
For bacteria with a polysaccharide coating, like Haemophilus influenzae type b, the best way to prevent infection is to use a conjugate vaccine. [1] A conjugate vaccine is a type of subunit vaccine which combines a weak antigen with a strong antigen as a carrier so that the immune system has a stronger response to the weak antigen.
T cells can then recognize these clippings and undergo a cellular transformation resulting in their own activation. [29] γδ T cells possess characteristics of both the innate and adaptive immune responses. Macrophages can also activate T cells in a similar approach (but do not do so naturally).
GVAX is a cancer vaccine composed of whole tumor cells genetically modified to secrete the immune stimulatory cytokine, granulocyte-macrophage colony-stimulating factor (GM-CSF), and then irradiated to prevent further cell division.
Attenuated vaccines function by encouraging the body to create antibodies and memory immune cells in response to the specific pathogen which the vaccine protects against. [8] Common examples of live attenuated vaccines are measles , mumps , rubella , yellow fever , and some influenza vaccines.
Cell mechanics is a sub-field of biophysics that focuses on the mechanical properties and behavior of living cells and how it relates to cell function. [1] It encompasses aspects of cell biophysics , biomechanics , soft matter physics and rheology , mechanobiology and cell biology .
