    Abstract Viral infections in an immunocompetent host can cause both acute and chronic kidney diseases, either by direct damage to the infected kidney cells or as a consequence of systemic immune responses that impact the kidneys' function. Viruses have evolved mechanisms to hijack signaling pathways of the infected cell, including the mammalian target of rapamycin pathway to support viral replication, and to evade antiviral immune responses such as those mediated by miR-155 via microRNA mimetics expressed by the virus. At both the cellular and systemic levels, the host has also evolved mechanisms to counter the viral subversion strategies in the evolutionary battle for mutual survival. In the era of genomic medicine, understanding individual genetic variations that lead to differences in susceptibilities to infection and variabilities in immune responses may open new avenues for treatment, such as the recently described functions of apolipoprotein L1 risk alleles in HIV-associated nephropathy. In addition, state-of-the-art high-throughput sequencing methods have discovered new viruses as the cause for chronic diseases not previously attributed to an infection. The potential application of these methods to idiopathic kidney diseases may reveal similar occult infections by unknown viruses. Precision medicine objectives to optimize host-directed and pathogen-directed therapies for kidney diseases associated with infectious causes will only be achieved through detailed understanding of genetic susceptibility associated with immune responses and viral tropism.

    Abstract Purpose of review: Allelic variants in the gene for apolipoprotein L1 (APOL1), found only in individuals of African ancestry, explain a majority of the excess risk of kidney disease in African Americans. However, a clear understanding how the disease-associated APOL1 variants cause kidney injury and the identity of environmental stressors that trigger the injury process have not been determined.
    Recent findings: Basic mechanistic studies of APOL1 biochemistry and cell biology, bolstered by new antibody reagents and inducible pluripotent stem cell-derived cell systems, have focused on the cytotoxic effect of the risk variants when APOL1 gene expression is induced. Since the APOL1 variants evolved to alter a key protein-protein interaction with the trypanosome serum resistance-associated protein, additional studies have begun to address differences in APOL1 interactions with other proteins expressed in podocytes, including new observations that APOL1 variants may alter podocyte cytoskeleton dynamics.
    Summary: A unified mechanism of pathogenesis for the various APOL1 nephropathies still remains unclear and controversial. As ongoing studies have consistently implicated the pathogenic gain-of-function effects of the variant proteins, novel therapeutic development inhibiting the synthesis or function of APOL1 proteins is moving toward clinical trials.

    Abstract Background: Hypertensive disorders of pregnancy cause fetal growth restriction and increased maternal morbidity and mortality, especially in women of African ancestry. Recently, preeclampsia risk was associated with polymorphisms in the apolipoprotein L1 (APOL1) gene in women of African ancestry.
    Objectives: We assessed APOL1 genotype effects on pregnancies with and without preeclampsia.
    Method: We conducted an unmatched case-control study of 1,358 mother-infant pairs from two independent cohorts of black women.
    Results: Term preeclampsia cases with high-risk APOL1 genotypes were more likely to be small for gestational age compared to APOL1 low-risk term cases (odds ratio [OR] 2.8) and APOL1 high-risk controls (OR 5.5). Among preterm pregnancies, fetal APOL1 genotype was associated with preeclampsia.
    Conclusions: Fetal APOL1 genotype was associated with preeclampsia in preterm infants and with altered fetal growth in term infants. This may indicate APOL1 genotype impacts a spectrum of pregnancy complications mediated by a common pathophysiological event of placental insufficiency.
