Genome, connections and frequency info Human endogenous retroviruses, HERVs for short, are among those biological topics that lie at the interface of genetics, virology and regulatory medicine. The literature describes numerous silent regions in the human genome that contain a large number of endogenous retroviruses and retroviral sequences. These sequencesContinue reading

Classification, immune system and frequency information HTLV-6, the human T-cell lymphotropic virus type 6, is described in the literature as a rare representative of the human lymphotropic retroviruses. Particular emphasis is placed on the connection with immunosuppressive conditions and with processes that can lead to tumor development in a broader sense.Continue reading

Classification, cell reference and frequency information HTLV-5, the human T-cell lymphotropic virus type 5, is one of the rarely mentioned representatives of the human lymphotropic retroviruses in the literature. It is mainly described in connection with DNA sequences isolated from tumor cells of patients with Tac antigen-negative cutaneous T-cell lymphoma leukemia or mycosis fungoides. TheseContinue reading

Classification, significance and frequency information HTLV-4, the human T-cell lymphotropic virus type 4, is one of the less frequently described representatives of the human lymphotropic retroviruses. The literature emphasizes that a fourth HTLV type has been described in African bushmeat hunters. It is precisely this observation that makes HTLV-4 virologically interesting, because it shows that even within theContinue reading

Basics, classification and frequency information HTLV-3, the human T-cell lymphotropic virus type 3, occupies a special position within the retroviruses. The literature describes that the term HTLV-3 was originally used in a different context, but later had to be reclassified. It is precisely this historical and virological development that makes HTLV-3Continue reading

Symptoms, course and frequency information HTLV-1, the human T-cell lymphotropic virus type 1, belongs to the group of retroviruses and is medically significant primarily due to its chronic course and possible long-term consequences. The literature describes that HTLV-1 can often persist unnoticed in the organism for a long time. At the same time, it is known,Continue reading

Basics, course and frequency information Human T-cell lymphotropic viruses, HTLV for short, belong to the group of retroviruses and occupy a special position within this virus family. The literature describes that several HTLV species are known to date and that these viruses usually establish a chronic, but often asymptomatic infection in humans.Continue reading

Basics, progression and frequency information Retroviruses belong to a medically particularly important group of viruses because they are characterized by an unusual reproduction mechanism. The literature describes that retroviruses use the enzyme reverse transcriptase to transcribe their genetic material from RNA into DNA. This viral DNA can then be integrated into the DNA using an integrase enzyme.Continue reading
