Experiences in immune reconstitution. The rationale for interleukin-2 administration to HIV-infected individuals

Abstract

Since the clinical earliest descriptions of patients with acquired immune deficiency syndrome (AIDS) it has been very clear that a profound state of immunologic dysfunction was the underlying cause of the emergence of life-threatening opportunistic infections and tumors. In addition to the progressive loss of CD4 "helper" T lymphocytes, a profound defect in interleukin-2 (IL-2) production was recognized as a major pathogenic component of the new disease. For these reasons, attempts to administer IL-2 to individuals infected with the human immunodeficiency virus (HIV), the causative agent of AIDS, have been made since the mid eighties, however with little success. On the other hand, the propensity of HIV to replicate in activated lymphocytes and macrophages, under the influence of the cytokine network, has represented, and in part still does, a major hurdle for the rationale of administering IL-2 or other cytokines to HIV-infected individuals. Major steps forward towards an understanding of the role of multiple components of the immune system, coupled with a potentially successful protocol of IL-2 administration in vivo, resulting in the stable uprising of circulating CD4+ T cells, shed an optimistic light on the possibility to ...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
