Key Difference – T Cell Dependent vs Independent Antigens In the context of immunology, antigens are specific molecules which have the ability to induce a particular immune response thereby producing antibodies accordingly. Antibodies are specific to antigens. Antigen presenting cells are a type of accessory cells that develop complexes with Major Histocompatibility Complexes (MHC) […]
Difference Between Epitope and Paratope
Key Difference – Epitope vs Paratope Immunological reactions take place in response to invasion by foreign bodies, especially pathogenic infectious organisms. Immune reactions can be of two different types; nonspecific mechanisms and specific mechanisms. Specific immune mechanisms involve a reaction between antibody and antigen thereby resulting in the destruction of the particular foreign body. […]
Difference Between Complete and Incomplete Antibodies
Key Difference – Complete vs Incomplete Antibodies Antibodies are composed of B cells and are immunoglobulins that take part in immune reactions. Antibodies can be of different classes depending on its structure, function, their type of reaction and the presence of accessory components. Antibodies are present in response to an antigen and thus, also […]
Difference Between Freund’s Complete and Incomplete Adjuvant
Key Difference – Freund’s Complete vs Incomplete Adjuvant Immunology is a vast area of study. It mainly involves in antigen-antibody reactions. These type of immunological reactions are used to identify a disease or the presence of foreign bodies such as infectious agents. Antigens are markers on pathogens which are mostly proteins. Some pathogens may contain […]
Difference Between Hapten and Antigen
Key Difference – Hapten vs Antigen Immunology is a broad field which teaches to identify and assess the manner in which an organism reacts upon exposure to a foreign body and protects it against the invasion. Immunological responses vary widely, and different defense mechanisms are discovered to explain the phenomenon. The immunological responses initiate […]
Difference Between H.pylori IGG and IGA
Key Difference – H.pylori IGG vs IGA Helicobacter pylori are spiral-shaped bacteria that cause gastrointestinal infections. H. pylori infection is one of the most common bacterial infection known to mankind across the world. World Health Organization has declared the Helicobacter pylori bacteria to be a Class 1 carcinogen which leads to gastrointestinal cancers and […]
Difference Between CD4 Cells and CD8 Cells
Key Difference – CD4 Cells vs CD8 Cells In the context of cell-mediated immunity, T cells, generally referred to T lymphocytes, play an important role. Since they mature in the thymus from thymocytes, they are referred to as T cells. T cells have two main categories: T helper (Th) cells and cytotoxic T cells (Tc). […]
Difference Between Coagulative and Liquefactive Necrosis
Key Difference – Coagulative vs Liquefactive Necrosis In the context of cell lysis, necrosis is a phenomenon of cell injury that results in autolysis, the premature death of different cells in tissues. This can occur due to external factors such as traumatic conditions to the cell, toxins, and infection. These factors cause the uncontrollable […]
Difference Between Hypersensitivity and Autoimmunity
Key Difference – Hypersensitivity vs Autoimmunity Autoimmunity is an adaptive immune response mounted against self-antigens. In simple terms, when your body is acting against its own cells and tissues, this is called an autoimmune reaction. An exaggerated and inappropriate immune response to an antigenic stimulus is defined as a hypersensitivity reaction. Unlike autoimmune reactions […]
Difference Between IgG and IgE
Key Difference- IgG vs IgE Immunoglobulins are a type of globular proteins with a complex structure which are produced by the living system as a secondary specific immune response upon contacting with a foreign particle or a pathogenic organism. Immunoglobulins are also known as antibodies or specific proteins produced in response to an antigen. […]
