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. […]
Difference Between Macrophages and Dendritic Cells
Key Difference – Macrophages vs Dendritic Cells Lymphocytes and phagocytes are two main types of immune cells. A phagocyte is a type of cell which is capable of engulfing and absorbing bacteria, other foreign cells, and infectious particles. There are two types of phagocytes: professional or non-professional phagocytes. The professional phagocytes are neutrophils, monocytes, macrophages, dendritic […]
Difference Between Myeloid and Lymphoid Cells
Key Difference – Myeloid vs Lymphoid Cells The bone marrow gives birth to different cells which are engaged in defense mechanisms of the body. Hematopoietic stem cells (hemocytoblasts) are the key cells produced in the bone marrow. Hematopoietic stem cells produce all other blood cells. The process of producing all blood cellular components from […]
Difference Between Mast Cell and Basophil
Key Difference – Mast Cell vs Basophil There are various types of immune cells in the immune system, including mast cells, natural killer cells, basophils, neutrophils, monocytes, B cells, T cells, macrophages, dendritic cells, and eosinophils. White blood cells play a major role in keeping you healthy by fighting off viruses, bacteria, parasites, and […]
Difference Between T Helper and T Cytotoxic Cells
Key Difference – T Helper vs T Cytotoxic Cells Lymphocytes are a type of white blood cells with a single round nucleus. They are important defense cells in vertebrates immune system. T cells or T lymphocytes are a subtype of lymphocytes. They are part of the adaptive immunity and are mainly involved in cell […]
Difference Between Primary and Secondary Immune Response
Key Difference – Primary vs Secondary Immune Response Humans and other animals live in an environment that is heavily populated by microorganisms. Some microbes are pathogenic and cause various types of infections. The immune system is the natural defense system of our body and the first line of defense designed to fight off against […]
