T-cells and transplantation tolerance in Thymectomised Xenopus implanted with foreign thymus [PDF]
This thesis investigates the expression of a T-cell differentiation antigen, (XTLA- 1), in various strains and species of Xenopus, and demonstrates the effect of early-thymectomy, (by microcautery), on XTLA-1 expression.

Calcium requirements during mitotic cdc2 kinase activation and cyclin degradation in Xenopus egg extracts. [PDF]
Activation of p34cdc2 kinase is essential for entry into mitosis while subsequent deactivation and cyclin degradation are associated with exit. In Xenopus embryos, both of these phases are regulated by post-translational modifications and occur ...

Activin, a member of the transforming growth factor (TGF-β) superfamily, induces mesoderm, endoderm and neuro-ectoderm formation in Xenopus embryos. Despite several previous studies, the complicated gene regulatory network and genes involved in this ...

Heterodimeric amino acid transporters consist of SLC7 and SLC3 family proteins arranged in a conserved structural organization. They regulate nutrient transport across cell membranes, supporting essential cellular functions. These transporters also contribute to xenobiotic/drug uptake and distribution.

In vitro studies on T cell proliferation and Lymphokine factor production in the amphibian, Xenopus [PDF]
The major aim of this Thesis has been to procure and begin to characterise T cell-derived cytokines in the clawed toad, Xenopus. Recent reports have suggested that Xenopus lymphocytes, stimulated in vitro with T cell mitogens, will generate factors that ...

Retinitis pigmentosa is an inherited retinal dystrophy that ultimately leads to blindness due to the progressive degeneration of rod photoreceptors and the subsequent non-cell autonomous death of cones.

Small RNA pathways in mammalian oocytes
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

Natural killer cell evolution: cellular and molecular studies on Xenopus [PDF]
The presence of natural killer cells at lower evolutionary levels was investigated in the amphibian Xenopus laevis. Chromium release microcytotoxicity assays revealed that fresh splenocytes from early-thymectomised Xenopus displayed significant ...

Xenopus has been one of the earliest and most important vertebrate model organisms for investigating the role and structure of basal bodies. Early transmission electron microscopy studies in Xenopus revealed the fine structures of Xenopus basal bodies and their accessory structures.
