Engineered B cells expressing an anti-HIV antibody enable memory retention, isotype switching and clonal expansion

open access: yesNature Communications, 2020
HIV viremia can be controlled by chronic antiretroviral therapy. As a potentially single-shot alternative, B cells engineered by CRISPR/Cas9 to express anti-HIV broadly neutralizing antibodies (bNAbs) are capable of secreting high antibody titers.

Flower-deficient mice have reduced susceptibility to skin papilloma formation

open access: yesDisease Models & Mechanisms, 2012
SUMMARY Skin papillomas arise as a result of clonal expansion of mutant cells. It has been proposed that the expansion of pretumoral cell clones is propelled not only by the increased proliferation capacity of mutant cells, but also by active cell ...

JunB Is Critical for Survival of T Helper Cells

open access: yesFrontiers in Immunology, 2022
Clonal expansion and differentiation of various T helper subsets, such as Th1, Th2, and Th17 cells, depend on a complex of transcription factors, IRF4 and a BATF-containing AP-1 heterodimer.

Autonomous B-cell receptor signaling and genetic aberrations in chronic lymphocytic leukemia-phenotype monoclonal B lymphocytosis in siblings of patients with chronic lymphocytic leukemia

open access: yesHaematologica, 2023
Clonal expansion of CD5-expressing B cells, commonly designated as monoclonal B lymphocytosis (MBL), is a precursor condition for chronic lymphocytic leukemia (CLL).

Longitudinal HIV sequencing reveals reservoir expression leading to decay which is obscured by clonal expansion

open access: yesNature Communications, 2019
After initiating antiretroviral therapy (ART), a rapid decline in HIV viral load is followed by a long period of undetectable viremia. Viral outgrowth assay suggests the reservoir continues to decline slowly.

The evolution of tumor metastases during clonal expansion [PDF]

open access: yesJournal of Theoretical Biology, 2010
Cancer is a leading cause of morbidity and mortality in many countries. Solid tumors generally initiate at one particular site called the primary tumor, but eventually disseminate and form new colonies in other organs. The development of such metastases greatly diminishes the potential for a cure of patients and is thought to represent the final stage ...

Endothelial cell clonal expansion in the development of cerebral cavernous malformations

open access: yesNature Communications, 2019
Cerebral cavernous malformation (CCM) is a neurovascular familial or sporadic disease that is characterised by capillary-venous cavernomas, and is due to loss-of-function mutations to any one of three CCM genes.

Dynamics and mechanisms of clonal expansion of HIV-1-infected cells in a humanized mouse model

open access: yesScientific Reports, 2017
Combination anti-retroviral therapy (cART) has drastically improved the clinical outcome of HIV-1 infection. Nonetheless, despite effective cART, HIV-1 persists indefinitely in infected individuals.

The Evolution of Two Mutations During Clonal Expansion [PDF]

open access: yesGenetics, 2007
Abstract Knudson's two-hit hypothesis proposes that two genetic changes in the RB1 gene are the rate-limiting steps of retinoblastoma. In the inherited form of this childhood eye cancer, only one mutation emerges during somatic cell divisions while in sporadic cases, both alleles of RB1 are inactivated in the growing retina.
