Generation of prolactin-inducible protein (Pip) knockout mice by CRISPR/Cas9-mediated gene engineering.
Title: Generation of prolactin-inducible protein (Pip) knockout mice by CRISPR/Cas9-mediated gene engineering.
we observed that the deficiency of Pip led to anomalies in the histology of lymphoid organs including the lymph nodes, spleen and thymus. We also observed anomalies in the morphology of the Eustachian tube and tympanic membrane in Pip deficient mice. Collectively, these data strongly suggest that Pip is an important regulator of immune responses.
Title: The prolactin inducible protein/gross cystic disease fluid protein-15 deficient mice develop anomalies in lymphoid organs.
studies show that deficiency of PIP significantly affects intracellular signaling events leading to decreased pro-inflammatory cytokine production, and further confirms a role for PIP as an important immunoregulatory protein. This direct link between PIP and cell-mediated immunity, a key component of the immune system that is critical for cancer control, may have significant therapeutic implications.
Title: The human breast cancer-associated protein, the prolactin-inducible protein (PIP), regulates intracellular signaling events and cytokine production by macrophages.
Recent work with Pip-deficient mice, linking PIP not only to a role in innate immunity but for the first time, providing evidence for a role in cell-mediated immunity. [Review]
Title: Prolactin-Inducible Protein: From Breast Cancer Biomarker to Immune Modulator-Novel Insights from Knockout Mice.
The findings implicate PIP as an important regulator of CD4(+) Th1-cell-mediated immunity.
Title: Deficiency of prolactin-inducible protein leads to impaired Th1 immune response and susceptibility to Leishmania major in mice.
these studies lend support to an immunomodulatory role for PIP in vivo and provide further insights into potentially novel signaling pathways and regulatory networks for PIP

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
