Progressive loss of CD3 expression after HTLV-I infection results from chromatin remodeling affecting all the CD3 genes and persists despite early viral genes silencing [PDF]

, 2007
BACKGROUND: HTLV-I infected CD4+ T-cells lines usually progress towards a CD3- or CD3low phenotype. In this paper, we studied expression, kinetics, chromatin remodeling of the CD3 gene at different time-points post HTLV-I infection. RESULTS: The onset of

Peripheral T‐Cell Lymphomas in Southern Taiwan: Epidemiology, Treatment Patterns, and Long‐Term Outcomes

eJHaem, Volume 7, Issue 3, June 2026.
ABSTRACT Peripheral T‐cell lymphomas (PTCLs) are heterogeneous neoplasms with poor prognosis and marked geographic variation. Data from Taiwan remain limited. We conducted a 15‐year retrospective cohort study of 249 patients diagnosed with PTCL at two major centers in southern Taiwan between 2010 and 2024 to characterize regional epidemiology, real ...

Is the innate bio-protection power against human virus the same between males and females? A conclusion based on blood donor data of HTLV-I infection [PDF]

, 2008
Human T-cell leukemia virus type I (HTLV-I) is a retrovirus that causes adult T-cell leukemia. The male-to-female transmission is stronger than the reverse, so the carrier proportion of women is greater than that of men.
