What acts as signals or markers to help cells recognize one another?
Cell surface markers, such as proteins and carbohydrates, play a key role in facilitating cell recognition. These markers are involved in cell-cell communication and help cells distinguish between self and non-self cells. Additionally, signaling molecules, such as cytokines and growth factors, can also serve as signals for cell recognition and interaction.
What typoes of cells produce antigens?
All cells produce antigens, or cell surface markers. The only question is whether the antigens are self antigens which means they belong in the body or they're foreign antigens which means they are an invading bacteria or virus (or a cancerous cell).
How Cell identification and recognition is a function of?
Cell identification and recognition is primarily a function of surface markers, such as proteins and carbohydrates, that are expressed on the cell membrane. These markers, often referred to as antigens, allow cells to communicate with each other and are crucial for processes like immune response, tissue formation, and cellular signaling. The interaction between these markers enables the immune system to distinguish between self and non-self cells, facilitating the body's defense against pathogens. Additionally, cell recognition plays a vital role in development, allowing cells to identify and interact with specific neighboring cells during tissue formation.
What proteins on surface of cells have carbohydrates attached to protein?
At the heart of the immune response is the ability to distinguish between "self" and "non-self." Every cell in your body carries the same set of distinctive surface proteins that distinguish you as "self." Normally your immune cells do not attack your own body tissues, which all carry the same pattern of self-markers; rather, your immune system coexists peaceably with your other body cells in a state known as self-tolerance. This set of unique markers on human cells is called the major histocompatibility complex (MHC). There are two classes: MHC Class I proteins, which are on all cells, and MHC Class II proteins, which are only on certain specialized cells.
Proteins in the cell membrane that identify the cell are called?
These proteins are called self markers. They tell the immune cells that they belong in the body and they should be attacked.Cell receptors (proteins) on the cell membrane mediate the inter cellular communications.
How does the immune system recognize its own body?
By recognizing self from non-self. Every cell in the body carries specific protein markers that are recognized by all immune cells so they do not attack self, at least when the system is operating well.
Which type of molecule is use as markers to help similar cells recognize each other?
Glycoproteins serve as markers on cell surfaces to help similar cells recognize each other. These molecules have carbohydrate chains attached to proteins, allowing cells to distinguish between self and non-self cells.

How do histocompatibility antigens help the immune system in recognizing and distinguishing between self and non-self cells?
Histocompatibility antigens, also known as human leukocyte antigens (HLAs), help the immune system recognize and distinguish between self and non-self cells by serving as markers on the surface of cells. These antigens play a crucial role in immune responses by allowing the immune system to identify and target foreign invaders while avoiding attacking the body's own cells.
What material acts like a marker on the outside of the cell for other cells?
At the heart of the immune response is the ability to distinguish between 'self' and 'non-self.'Every cell in your body carries the same set of distinctive surface proteins that distinguish you as 'self.'

How does the body identifies its own cells?
The body uses surface markers called antigens to identify its own cells. These antigens are like a cellular ID card that tells the immune system that the cell is part of the body and not a foreign invader. Cells that display these self-identifying antigens are generally spared from attack by the immune system.
What is mostly likely to happen in a lymph node?
a. attachment of MHC markers to self cells b. production of B and T lymphocytes c. phagocytosis of organisms foreign to the body d. oxygenation of the interstitial fluid e. destruction of red blood cells and recycling of their contents
How do phagocytes recognize cancerous cells from healthy cells?
Phagocytes recognize cancerous cells through differences in surface markers, such as altered proteins or glycoproteins that are often overexpressed or mutated in tumors. These abnormal markers can trigger immune responses, allowing phagocytes to identify and engulf the cancerous cells. Additionally, cancer cells may lack certain "self" markers that healthy cells possess, making them more recognizable as foreign by the immune system. Through these mechanisms, phagocytes play a crucial role in detecting and eliminating cancerous cells.
