477:(COVID-19) pneumonia in two patients with lung cancer after a biopsy. Specifically, they were located in inflammatory fibrin clusters, sometimes together with mononuclear inflammatory cells. Another pathological study also detected this type of giant cell in COVID-19 and described it as a "multinucleated syncytial cell". The morphological analysis showed that multinucleated syncytial cells and atypical enlarged pneumocytes demonstrating cytomorphological changes consistent with viral infection were found in the intra-alveolar spaces. The viral antigen was detected in the cytoplasm of multinucleated syncytial cells, indicating the presence of the SARS-CoV-2 virus. However, a later post-mortem study has described these cells as 'giant cell-like' rather than true giant cells derived from histiocytes. Instead, they are derived from type II pneumocyte clusters with 134: 369: 377: 20: 164:, diseases, and cell formations. Giant cells are also known to develop when infections are present. They were first observed as early as the middle of the last century, but it is not fully understood why these reactions occur. In the process of giant cell formation, monocytes or macrophages fuse together, which could cause multiple problems for the immune system. 440:
Some researchers have conjectured that Giant cells may be instrumental in the formation of tumours, and that their origin may be in the stress-induced genomic reorganization proposed by Nobel Laureate Barbara McClintock. It had previously been suggested that such genomic stress could be aggravated by

This type of giant cell could be caused by bacteria that spread from person to person through the air. Tuberculosis is related to HIV; many people who have HIV also have a hard time fighting off diseases and sicknesses. Many tests may be performed to treat other related diseases to obtain the correct

Langhans giant cells are named for the pathologist who discovered them, Theodor Langhans. Like many of the other kinds of giant cell formations, epithelioid macrophages fuse together and form a multinucleated giant cell. The nuclei form a circle or semicircle similar to the shape of a horseshoe away

Osteoclasts are the most prominent examples of MGCs and are responsible for the resorption of bones in the body. Like other MGCs, they are formed from the fusion of monocyte/macrophage precursors. However, unlike other MGCs, the fusion pathway they originate from is well elucidated. They also do not

Northern Europeans have been observed to have a higher incidence of giant cell arteritis compared to southern European, Hispanic, and Asian populations. It has been suggested that this difference may lie in the criteria used to diagnose giant cell arteritis rather than actual disease incidence, in

Osteoclasts were discovered in 1873. However, it was not until the development of the organ culture in the 1970s that their origin and function could be deduced. Although there was a consensus early on about the physiological function of osteoclasts, theories on their origins were heavily debated.

foreign materials. However, their large size and extensive membrane ruffling make them better equipped to clear up larger particles. They utilize activated CR3s to ingest complement-opsonized targets. Non-osteoclast MGCs are also responsible for the clearance of cell debris, which is necessary for

Reed-Sternberg cells are generally thought to originate from B-lymphocytes. They are hard to study due to their rarity, and there are other theories about the origins of these cells. Some less popular theories speculate that they may arise from the fusion between reticulum cells, lymphocytes, and

Osteoclasts are typically associated more with healthy physiological functions than they are with pathological states. They function alongside osteoblasts to remodel and maintain the integrity of bones in the body. They also contribute to the creation of the niche necessary for hematopoiesis and

Coronavirus disease 2019 (COVID-19) is caused by a novel coronavirus called SARS-CoV-2. Multinucleated giant cells have been detected in biopsy specimens from patients with COVID-19 disease. This type of giant cell was first found in pulmonary pathology of early phase 2019 novel coronavirus

are a type of MGC that are critical for the maintenance, repair, and remodeling of bone and are present normally in a healthy human body. Osteoclasts are frequently classified and discussed separately from other MGCs which are more closely linked with disease.
401:. As with other types of giant cells, epithelioid macrophages fusing together causes these giant cells to form and grow. In this form of giant cell, the nuclei are arranged in an overlapping manner. This giant cell is often found in tissue because of 208:

Symptoms may include a mild fever, loss of appetite, fatigue, vision loss, and severe headaches. These symptoms are often misinterpreted leading to a delay in treatment. If left untreated, this disease can result in permanent blindness.

Similar to other MGCs, Reed-Sternberg cells are large and are either multinucleated or have a bilobed nucleus. Their nuclei are irregularly shaped, contain clear chromatin, and possess an eosinophilic nucleolus.
187:. However, while the primary functions of osteoclasts are integral to maintaining a healthy physiological state, they have also been linked to osteoporosis and the formation of bone tumors. 216:
Giant cell arteritis is most prevalent in older individuals, with the rate of disease being seen to increase from age 50. Women are 2–3 times more likely to develop the disease than men.
