“…As CD8 + T cells express IL-2Rβγ and immunosuppressive Tregs constitutively express IL-2Rαβγ, these findings suggest that the latent cytokine may improve CD8 + /Treg ratios, which are prognostically favorable in many cancers 39 and correlate with clinical responses to an immune checkpoint blockade therapy in patients. 40 While other mechanisms of cytokine receptor subunit-biasing based on mutagenesis, 41,42 antibody complexation, 43 and de novo protein design 44 have been reported, here, we hypothesize that atypically high density of solvent-accessible lysine resides at the IL-2/IL-2Rα interface preferentially induces steric hindrance with the receptor subunit via appended polymer chains. 24 In addition to demonstrating rapid and efficient cytokine photoactivation, we also found that polymer photocages used here were highly stable under conditions simulating both aqueous storage and venous ambient light exposure.…”

The first observational evidence for the cosmic acceleration appeared from the type Ia supernovae (SNe Ia) Hubble diagram from two different groups. However, the empirical treatment of SNe Ia and their ability to show cosmic acceleration have been the subject of some debate in the literature. In this work we probe the assumption of redshift-independent absolute magnitude (M B ) of SNe along with its correlation with spatial curvature (Ω k0 ) and cosmic distance duality relation (CDDR) parameter (η(z)). This work is divided into two parts. Firstly, we check the validity of CDDR which relates the luminosity distance (d L ) and angular diameter distance (d A ) via redshift. We use three different redshift-dependent parametrizations of the distance duality parameter (η(z)). CDDR is fairly consistent for almost every parametrization within 95% confidence level in both flat and non-flat universe. However, one of the parametrizations does not validate CDDR in the case of a non-flat universe. In second part, we take the validity of CDDR for granted and emphasise on the variability of M B and its correlation with Ω k0 . We choose three different redshift-dependent parametrizations of M B . The results indicate no evolution of M B at 99% confidence level but clearly indicates the inclination towards a non-flat open universe. We further extend our analysis and examine the dependence of the results on the choice of different priors for H 0 .

Strong lensing systems and galaxy cluster observations as probe to the cosmic distance duality relation

et al. 2022

In this paper, we use large scale structure observations to test the redshift dependence of cosmic distance duality relation (CDDR), $$D_\mathrm{L}(1+z)^{-2}/D_\mathrm{A}=\eta (z)$$ D L ( 1 + z ) - 2 / D A = η ( z ) , with $$D_\mathrm{L}$$ D L and $$D_\mathrm{A}$$ D A , being the luminosity and angular diameter distances, respectively. In order to perform the test, the following data set are considered: strong lensing systems and galaxy cluster measurements (gas mass fractions). No specific cosmological model is adopted, only a flat universe is assumed. By considering two $$\eta (z)$$ η ( z ) parametrizations, It is observed that the CDDR remain redshift independent within $$1.5\sigma $$ 1.5 σ which is in full agreement with other recent tests involving cosmological data. It is worth to comment that our results are independent of the baryon budget of galaxy clusters.
