Mucosal integrin α4β7 blockade fails to reduce the seeding and size of viral reservoirs in SIV-infected rhesus macaques.
Article in FASEB journal : official publication of the Federation of American Societies for Experimental Biology, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 7 papers, 1 of them a synthesis that pooled it.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Cellular viral reservoirs are rapidly established in tissues upon HIV-1/SIV infection, which persist throughout viral infection, even under long-term antiretroviral therapy (ART). Specific integrins are involved in the homing of cells to gut-associated lymphoid tissues (GALT) and inflamed tissues, which may promote the seeding and dissemination of HIV-1/SIV to these tissue sites. In this study, we investigated the efficacy of prophylactic integrin blockade (α4β7 antibody or α4β7/α4β1 dual antagonist TR-14035) on viral infection, as well as dissemination and seeding of viral reservoirs in systemic and lymphoid compartments post-SIV inoculation. The results showed that blockade of α4β7/α4β1 did not decrease viral infection, replication, or reduce viral reservoir size in tissues of rhesus macaques after SIV infection, as indicated by equivalent levels of plasma viremia and cell-associated SIV RNA/DNA to controls. Surprisingly, TR-14035 administration in acute SIV infection resulted in consistently higher viremia and more rapid disease progression. These findings suggest that integrin blockade alone fails to effectively control viral infection, replication, dissemination, and reservoir establishment in HIV-1/SIV infection. The use of integrin blockade for prevention or/and therapeutic strategies requires further investigation.
