Lysis in Biological Definition

Lysis

Lysis ( Greek lusis from luein = to separate) is the reduction of symptoms of a disease the dissolving of cells known more specifically as cytolysis osmotic lysis chemical lysis viral lysis a dialogue of Plato about friendship ( philia ), see Lysis (...

Alexander Fleming

... Fleming inspected the Petri dish further and found that the bacterial colonies around the fungus were transparent because their cells were lysing . lysis is the breakdown of cells, and in this case, potentially harmful bacteria. The importance was immediately recognized, however the discovery was still...

Antibody

...ds to various cell receptors and complement proteins. In this way it mediates different physiological effects of antibodies ( opsonization , cell lysis , mast cell, basophil and eosinophil degranulation and other processes). The variable regions of the heavy and light chains can be fused together t...

Antigen

...ex with class I histocompatibility molecules . If cytotoxic CD8 + T cells recognize them, they begin to secrete different toxins that cause the lysis or apoptosis of the infected cell. In order to keep the cytotoxic cells from killing cells just for presenting normal proteins, they run through a ...

Glycolysis

...result in the formation of ATP. These two reactions pull the glycolytic pathway to completion. Etymology From Greek glyk meaning sweet and lysis meaning dissolving. See also Gluconeogenesis Krebs cycle Anaerobic respiration External links The Glycolytic enzymes in G...

Lytic cycle

... 1 Description 1.1 Infection 1.2 Growth 1.3 Replication and lysis Description The lytic cycle is a three-stage process. I...A into DNA, which is then transcribed again into mRNA. Replication and lysis After many virus copies are made, they are assembled into complete viruse...

Peptide

...for a wide array of functions, many of which are not yet understood. Antimicrobial peptides generally disrupt the membranes of a target cell, causing lysis of the cell. How this occurs, and what determines the activity and selectivity of these peptides, is currently only known approximately. It has als...

Phage

...igns of stress (meaning it might be about to die soon), the endogenous phages become active again and start their reproductive cycle, resulting in the lysis of the host cell. An example is phage λ of E. coli . Sometimes, prophages even provide benefit to the host bacterium while they are dormant,...

Virus

...haperones , or proteins made by the host that help the capsid parts come together. The new viruses then leave the cell either by exocytosis or by lysis . Envelope-bound animal viruses instruct the host's endoplasmic reticulum to make certain proteins, called glycoproteins , which then collect in cl...
