Immune modulatory vaccines (IMVs) are novel therapies designed to activate anti-regulatory T cells (anti-Tregs) [1]. Anti-Tregs recognize HLA-restricted antigens on the surface of regulatory immune cells derived from tumor microenvironment antigens (TMAs) [2], such as IDO [3], PD-L1 [4], and TGFβ [5, 6]. Having established that specific T cells recognize target cells in a TGFβ-dependent manner, we reported that such TGFβ-specific T cells are associated with clinical benefit and improved survival after combined treatment with radiotherapy (RT) and immune checkpoint inhibitors (ICIs) in patients with pancreatic cancer (PC) [7]. Additionally, we found that a TGFβ-based IMV impacted tumor growth in murine models of PC via immune modulation of the tumor microenvironment (TME) [8]. These data suggest that combining a TGFβ-based IMV with RT/ICI therapy will be beneficial for patients with PC.

Tumor necrosis factor-α (TNF-α) inhibitors are biological agents introduced in the late 1990s for the treatment of different immune-mediated diseases as inflammatory bowel disease, rheumatoid arthritis and psoriasis. The most commonly used TNF-α antagonists are infliximab, adalimumab, and certolizumab pegol, and though highly effective in lowering inflammation, the efficacy must be weighed against the potential for adverse events. The treatment-induced immunosuppression is suspected to increase the risk of infections, including the risk of reactivation of latent tuberculosis, as the TNF-α cytokine plays an important role in the immune function. In this topic highlight a short overview of the infection risk associated with TNF-α inhibiter therapy is outlined with a focus on the overall risk of serious infections, mycobacterial infection and latent viral infections.

We propose a new two-phase method for reconstruction of blurred im-ages corrupted by impulse *** the first phase,we use a noise detector to iden-tify the pixels that are contaminated by noise,and then,in the second phase,we reconstruct the noisy pixels by solving an equality constrained total variation mini-mization problem that preserves the exact values of the noise-free *** images that are only corrupted by impulse noise(i.e.,not blurred)we apply the semismooth Newton’s method to a reduced problem,and if the images are also blurred,we solve the equality constrained reconstruction problem using a first-order primal-dual *** proposed model improves the computational efficiency(in the denoising case)and has the advantage of being regularization *** numerical results suggest that the method is competitive in terms of its restoration capabilities with respect to the other two-phase methods.
