The cytotoxic t cell directly attacks and lyses cellular pathogens. They are activated by antigens that stimulate an immune response.

One mechanism that directly attacks and lyses cellular pathogens is the complement system. This system consists of a group of proteins that can form pores on the cell membranes of pathogens, leading to cell lysis. Additionally, certain immune cells, such as natural killer cells or cytotoxic T cells, can release toxic substances that directly kill pathogens.

What happens to a cell when it lyses?
When a cell lyses, its membrane breaks open, causing the cell to burst and release its contents into the surrounding environment. This can occur due to physical damage, osmotic stress, or the actions of certain enzymes or toxins.
What is the function of sodium deoxycholate in media?
Sodium deoxycholate is a detergent commonly used in cell culture media to disrupt lipid membranes and solubilize membrane proteins. It helps in cell lysis, protein extraction, and is often used in combination with other detergents to maintain the solubility of membrane proteins in solution.
What might happen to a cell after viruses leave it?
The host cell lyses, which means the host cell burst and is killed.
What lyses the cell wall?
Enzymes called lysozymes can lyse bacterial cell walls by breaking down the peptide bonds in the peptidoglycan layer. Other substances, such as detergents or antibiotics, can also disrupt and lyse cell walls by affecting membrane integrity or cell wall synthesis.
What is th role of dnazol in dna extraction?
DNAzol is a reagent used in DNA extraction to lyse cells by disrupting the cell membrane and nucleus. It helps release DNA from the cells and proteins, allowing for subsequent separation and purification of the DNA. DNAzol also helps protect the DNA from degradation during the extraction process.
Directly attacks and lyses cellular pathogens?
B lymphocytes
What is cellular waste?
Cellular waste refers to byproducts of cellular metabolism that are no longer needed by the cell and can be harmful if they accumulate. These waste products are typically in the form of substances like carbon dioxide, urea, and other metabolic byproducts that need to be efficiently removed from the cell to maintain cellular health and function. Cells have mechanisms to process and eliminate these waste products to maintain homeostasis.

What is lytic reproduction?
ex. a virus enters a cell, replicates, and then "lyses" (ruptures) the cell. those virus particles are now free to infect other cells.
What happens to the viruses after they lyse the cell wall?
After the viruses lyse the cell wall, they release new viral particles that can infect other cells in the body. This continues the cycle of viral replication and infection.
What is the function of sodium deoxycholate in media?
Sodium deoxycholate is a detergent commonly used in cell culture media to disrupt lipid membranes and solubilize membrane proteins. It helps in cell lysis, protein extraction, and is often used in combination with other detergents to maintain the solubility of membrane proteins in solution.
What is viruses used for?
Viruses are used to infect host cells and replicate themselves by hijacking the cell's machinery. In biotechnology, viruses are modified to deliver genetic material into cells for research purposes or to treat genetic diseases. Additionally, certain viruses are used as vectors in gene therapy to introduce therapeutic genes into specific cells.
Should early morning blood sample be given for diagnosis of malaria?
No, the blood sample for malaria should be given when the patient is febrile (has a fever). In malaria the fever cycles on and off. In the febrile period the parasite is visible as it lyses the blood cells and escapes the liver.
