Cytotoxic T cells are a type of cell that destroys body cells infected with microbes. They recognize infected cells by detecting specific antigens on their surface and then release toxic substances to kill the infected cell.
The protein that punches holes into the plasma membrane of an infected host cell is called a pore-forming protein. These proteins create pores that disrupt the cell membrane's integrity, leading to cell lysis and death.
More viruses. Cells infected with virus DNA are essentially converted into virus factories. Instead of producing the materials the cell needs to reproduce, it produces dormant viruses, until the cell bursts and the new viruses begin infecting other cells.
In an infected cell, the pathogen, such as a virus, hijacks the cell's machinery to replicate itself. This often leads to the production of new viral particles, which can then cause cell damage or death. As the cell's resources are depleted and its normal functions are disrupted, it may undergo apoptosis or lysis, releasing the newly formed pathogens to infect neighboring cells. This process contributes to the spread of the infection within the host.
CD8+ cytotoxic T cells are primarily responsible for identifying and eliminating infected or cancerous cells. They recognize infected cells through the presentation of foreign antigens on MHC class I molecules. When a CD8+ T cell detects an abnormality, such as a viral infection, it can initiate a response to kill the compromised cell. Additionally, CD4+ helper T cells can also play a role in orchestrating the immune response by supporting other immune cells.
The cell infected by a virus is referred to as the host cell. The virus hijacks the host cell's machinery to replicate and produce more virus particles.
no, that is supplied by the infected cell.
CD8 T cells kill infected cells by releasing proteins called perforins and granzymes. Perforins create pores in the infected cell's membrane, allowing granzymes to enter and trigger cell death. This process helps eliminate the infected cell and stop the spread of the infection.
It is called a host cell. The virus attaches to the cell and injects its DNA into the cell. The virus's DNA overruns the "instructions" that the cell has and "tells" the cell to make copies of the virus using the DNA. Then the cell makes so many copies of the virus, that it explodes. The new viruses then go on to attach to other cells.

The components of a virus that is injected into the infected cell is either the RNA or DNA. A virus is composed of two parts a nucleic acid part and a protein part.
The genetic material of a virus, either DNA or RNA, is injected into an infected cell. This genetic material contains the instructions needed for the virus to hijack the cell's machinery and replicate itself.

Cytotoxic T cells kill infected or abnormal cells by releasing toxic substances that puncture the cell membrane, triggering cell death.
