VIRUSES Flashcards
(44 cards)
a small amount of DNA surrounded by a
protein envelope
virus
a retrovirus that attacks the immune system and is
the causative agent of AIDS
human immunodeficiency virus (HIV
a disease caused by the human immunodeficiency
virus, which is characterized by low T cell counts
leading to infections that often prove fatal
acquired immunodeficiency syndrome (AIDS)
a complete virus particle consisting of
nucleic acid and coat protein
virion
the protein coat of a virus
capsid
s a small amount of genetic material surrounded by
a protein envelope
Virus
They are pathogens
of
bacteria, plants, and animals.
The classic viral shape most
often seen in the literature has
hexagonal capsid, rod sticking
a method for treating a genetic
disease by introducing a good copy of a defective
gene
gene therapy
a genetic disease that affects DNA synthesis in the
cells of the immune system
severe combined immune deficiency (SCID)
a vector
commonly used in gene therapy
Maloney murine leukemia virus (MMLV)
in gene therapy, the
assemblage that contains the gene being
transferred
expression cassette
a simple DNA virus that is often used
for gene therapy
adenovirus
the proteins that make up the
capsid or protein coat that surrounds the genetic
material of a virus
coat proteins (CP)
the enzyme that
directs the synthesis of DNA on an RNA template
reverse transcriptase (RT)
proteins found in the
outer membrane of a virus
envelope proteins (EP
a disease in which
the immune system attacks the body’s
own tissues
Auto immune disease
a weakened or killed form of an infectious agent that is injected into an organism so that it will
make antibodies against the true infectious agent
Vaccine
white blood cells that play an important
role in the functioning of the immune system
leukocytes
the first line of defense in the
immune system
innate immunity
innate immunity cells that are the
first to encounter viruses or bacteria
dendritic cells
cells of the innate immune system
that digest cellular debris and pathogens
macrophages
cells of the innate
immune system that kill cells which have been
infected or are cancerous
natural killer (NK) cells
protein that displays an antigen on the surface of
cells of the immune system
major histocompatibility complex (MHC)
