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

Transmission, course and complementary observation The human immunodeficiency virus is one of the most medically significant retroviruses because it can gradually impair the immune system. The literature describes that HIV primarily attacks lymphocytes, which can lead to acquired immunodeficiency. In advanced stages, this can lead to severe secondary diseases, opportunistic infections and certainContinue reading

Lentiviruses belong to the family of retroviruses and are characterized by a special biological mechanism. They are described in the literature as a virus group that differs from the human T-cell lymphotropic viruses and can trigger profound chronic processes in humans. The focus is particularly onContinue 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

HTLV-2, the human T-cell lymphotropic virus type 2, belongs to the group of retroviruses and is closely genetically related to HTLV-1. The literature describes a pronounced homology of the nucleic acids, but HTLV-2 must nevertheless be distinguished from HTLV-1 as an independent virus type. EspeciallyContinue reading
