Cells of the immune system, such as T cells and B cells, play a crucial role in identifying and distinguishing pathogens. T cells recognize specific antigens presented by infected cells and trigger an immune response, while B cells produce antibodies that bind to antigens on pathogens, marking them for destruction by other immune cells. This process allows the immune system to target and eliminate a wide variety of pathogens efficiently.
Cells that identify pathogens and distinguish one from another are called antigen-presenting cells (APCs), such as dendritic cells, macrophages, and B cells. These cells play a key role in activating the immune response by presenting antigens to other immune cells, like T cells, to initiate a targeted immune response against the specific pathogen.
On human cells MHC molecules are used to identify cancerous cells. On bacterial cells things like LPS and various surface proteins are identified as "foreign" The problem with this is that not all molecules that are used to identify "friend or foe" are attached to the surface. Things like non-methylated CpG, LPS, peptidoglycan and dsRNA all activate PRRs in cells, leading to an immune response. If you want a more comprehensive answer please contact me.
Cells of the immune system, such as macrophages and dendritic cells, mark pathogens for destruction by presenting antigens on their surface to activate other immune cells like T cells. This process helps the immune system identify and target foreign invaders for elimination.
They transform themselves to lots of plasma cells, which create antibodies to fight against the pathogens.

The basic function of activated T cells is to identify and destroy cells infected with pathogens or cells that are abnormal, such as cancer cells. They achieve this through the recognition of specific antigens presented on the surface of target cells. Additionally, activated T cells can also help regulate the immune response by releasing signaling molecules that influence other immune cells.
pathogens live inside the live cells
Yes. Antibodies do prevent pathogens from infecting other cells.
No. Hand sanitizers on your hands just kill pathogens (Pathogens is another word for germs, if you don't know what it means). The pathogens can't evade the alcohol. If they do, they may kill your brain cells. I do not know about other alcohols, but of course, it won't kill your brain cells if it doesn't have to do with killing germs. That was a very good question, anyway.

The immune system of the body provide a defense against abnormal cells and pathogens inside living cells. Generally this results into rise in temperature of the body. Therefore, fever is the indication of having war against abnormal cells and pathogens.
