Interferons and HIV Infection: The Good, the Bad, and the Ugly.

Pathogens & immunity

Utay NS, Douek DC.
PMID: 27500281
Pathog Immun. 2016;1(1):107-116. doi: 10.20411/pai.v1i1.125.

Whether type I interferons (IFNs) hinder or facilitate HIV disease progression is controversial. Type I IFNs induce the production of restriction factors that protect against mucosal HIV/SIV acquisition and limit virus replication once systemic infection is established. However, type...

Deep Time Course Proteomics of SARS-CoV- and SARS-CoV-2-Infected Human Lung Epithelial Cells (Calu-3) Reveals Strong Induction of Interferon-Stimulated Gene Expression by SARS-CoV-2 in Contrast to SARS-CoV.

Journal of proteome research

Grossegesse M, Bourquain D, Neumann M, Schaade L, Schulze J, Mache C, Wolff T, Nitsche A, Doellinger J.
PMID: 34982558
J Proteome Res. 2022 Jan 04; doi: 10.1021/acs.jproteome.1c00783. Epub 2022 Jan 04.

Severe acute respiratory syndrome (SARS)-CoV and SARS-CoV-2 infections are characterized by remarkable differences, including infectivity and case fatality rate. The underlying mechanisms are not well understood, illustrating major knowledge gaps of coronavirus biology. In this study, protein expression of...

The combination of TRAIL and the Smac mimetic LCL-161 induces an irreversible phenotypic change of MCF-7 breast cancer cells.

Experimental and molecular pathology

Granqvist V, Holmgren C, Larsson C.
PMID: 35007560
Exp Mol Pathol. 2022 Jan 07;104739. doi: 10.1016/j.yexmp.2021.104739. Epub 2022 Jan 07.

BACKGROUND: Breast cancer is the most common malignancy affecting women. Although the prognosis generally is good, a substantial number of patients still suffer from relapse, emphasizing the need for novel treatments. Smac mimetics were developed to facilitate cell death...

COVID-19 skin lesions are rarely positive at RT-PCR test: the macrophage activation with vascular impact and SARS-CoV-2-induced cytokine storm.

International journal of dermatology

Ionescu MA.
PMID: 34213786
Int J Dermatol. 2022 Jan;61(1):3-6. doi: 10.1111/ijd.15749. Epub 2021 Jul 02.

BACKGROUND: Several skin manifestations have been reported since the start of the COVID-19 pandemic: chilblains-like, livedoid lesions, urticaria-like, pseudo-Kawasaki disease, and others. Histopathologic images of these lesions most often show aspects of endothelitis, images similar to autoimmune vasculitis. Cutaneous...

COVID-19 in Immunosuppressed Children.

Frontiers in pediatrics

Nicastro E, Verdoni L, Bettini LR, Zuin G, Balduzzi A, Montini G, Biondi A, D'Antiga L.
PMID: 33996683
Front Pediatr. 2021 Apr 29;9:629240. doi: 10.3389/fped.2021.629240. eCollection 2021.

Following the spread of the SARS-CoV-2 infection and coronavirus disease 2019 (COVID-19) to a global pandemic, concerns have arisen for the disease impact in at-risk populations, especially in immunocompromised hosts. On the other hand, clinical studies have clarified that...

Hematopoietic Stem Cell Regulation by Type I and II Interferons in the Pathogenesis of Acquired Aplastic Anemia.

Frontiers in immunology

Smith JN, Kanwar VS, MacNamara KC.
PMID: 27621733
Front Immunol. 2016 Aug 29;7:330. doi: 10.3389/fimmu.2016.00330. eCollection 2016.

Aplastic anemia (AA) occurs when the bone marrow fails to support production of all three lineages of blood cells, which are necessary for tissue oxygenation, infection control, and hemostasis. The etiology of acquired AA is elusive in the vast...

The dUTPase of caprine arthritis-encephalitis virus negatively regulates interferon signaling pathway.

Iranian journal of veterinary research

Shi J, Li X, Zhu M, Chi H, Song Y, Wang J, Huang J.
PMID: 34777521
Iran J Vet Res. 2021;22(3):209-216. doi: 10.22099/ijvr.2021.38240.5568.

BACKGROUND: Deoxyuracil triphosphate nucleotide (dUTP) pyrophosphatase (dUTPase, DU) is an enzyme of caprine arthritis-encephalitis virus (CAEV) that minimizes incorporation of dUTP into the DNA. Caprine arthritis-encephalitis virus relies partly on its ability to escape from innate immunity to cause...

Type I Interferon Impairs Specific Antibody Responses Early during Establishment of LCMV Infection.

Frontiers in immunology

Daugan M, Murira A, Mindt BC, Germain A, Tarrab E, Lapierre P, Fritz JH, Lamarre A.

Front Immunol. 2016 Dec 05;7:564. doi: 10.3389/fimmu.2016.00564. eCollection 2016.

Elicitation of type I interferon (IFN-I) has been shown to both enhance and impair cell-mediated immune responses in acute and persistent viral infections, respectively. Here, we show that, in addition to its effect on T cells, IFN-I drives impairment...
