According to recent studies from the NIH HIV Reagent Program and the American Society for Microbiology , tazarotene acid is being investigated for the following:

While "21367.rar" might occasionally appear as a generic archive filename in legacy datasets, the number is most prominently associated with this specific biochemical reagent in scientific literature as of early 2026 [14, 21].

: Research indicates it significantly enhances Natural Killer (NK) cell natural cytotoxicity and antibody-dependent cellular cytotoxicity (ADCC) against HIV-infected CD4 T cells [14, 21].

: It functions by increasing the expression of CD16 on NK cells, which improves their ability to recognize and destroy infected targets [14]. Technical Specifications Catalog Number 21367 (Commonly via Cayman Chemical) [21] Class

Elimination of latent HIV reservoirs and dermatological efficacy [14]

Tazarotene acid is the active carboxylic acid metabolite of the prodrug tazarotene [21]. It functions as a selective retinoid X receptor (RXR) and retinoic acid receptor (RAR) agonist, specifically targeting and RAR- [14]. Key Research Applications

: It has been identified as a compound capable of sensitizing latently infected HIV cells to apoptosis [14, 21].

The identification of "" as a chemical catalog number for Tazarotene Acid is the primary lead for this write-up [21]. This compound is a major metabolite of the FDA-approved retinoid Tazarotene and is a significant subject in immunological and dermatological research [14, 21]. Overview: Tazarotene Acid (Item #21367)
