Adoptive T cell therapy (ACT) in combination with lymphodepleting chemotherapy is an effective strategy to induce the eradication of tumors, providing long-term regression in cancer patients. However, only a minority of patients that receive ACT with tumor infiltrating lymphocytes (TILs) exhibit durable benefit. Thus, there is an urgent need to define strategies that potentiate anti-tumor activity conducted by adoptively transferred T cells. In these studies, we aimed to identify novel strategies to enhance the therapeutic efficacy of ACT. Accordingly, we describe the disparate roles of myeloid cells in the context of ACT characterized by the augmentation of TIL proliferation in …
Non-Invasive Sex Determination And Genotyping Of Transgenic Brugia Malayi Larvae, Santiago E. Hernandez Bojorge

Lymphatic filariasis is a very painful and disfiguring helminth disease caused by the tissue nematodes Wuchereria bancrofti, Brugia malayi, and Brugia timori. This parasitosis is considered a Neglected Tropical Disease and it is a major public health burden for 72 tropical countries of Africa, Southeast Asia, the Caribbean, and South America. Despite the effectiveness of many control programs, there remains the need to develop new pharmacological agents to treat lymphatic filariasis, as most programs rely on a limited variety of drugs that are expensive, logistically difficult to obtain, and can lead to drug resistance. The Clustered Regularly Interspaced Short Palindromic …

The discovery and implementation of immunomodulatory drugs (IMiD®s) has revolutionized the treatment of many hematological malignancies due to the plethora of IMiD®-induced clinical responses that include anti-angiogenesis, anti-inflammation, and anti-tumor effects, as well as enhanced erythropoiesis, immune modulation and improved metabolism. More ground-breaking was the identification of cereblon as the target of IMiD®s. Upon binding to thalidomide and other immunomodulatory drugs, the E3 ligase substrate receptor cereblon (CRBN) promotes proteosomal destruction of neo-substrates by engaging the DDB1-CUL4A-Roc1-RBX1 E3-ubiquitin ligase in human cells but not in mouse cells suggesting that sequence variations in CRBN may cause its inactivation. Therapeutically, CRBN engagers …

The immune system plays a dynamic role in cancer progression. The theory of immunoediting suggests that the relationship between the tumor cell and the immune cell is one that is in flux: initially highly active and responsive to tumor antigen to one that has escaped immune responsiveness. Once the tumor has formed and effectively “escaped”, there are multiple mechanisms that work against a conventional immune response. The tumor cell clones that have escaped the elimination phase are those that are less immunogenic. These clones downregulate MHC, have increased apoptosis through DAMP-driven mechanisms, and suppressive cell phenotypes are driven through cytokine-driven …
