Oncoprotein-Specific Recombinant Antibodies for HPV Tumour Therapy
Human papillomaviruses (HPVs) are involved in the development of around 5% of all human cancers and HPV16 is the high-risk genotype with the highest prevalence worldwide, playing a dominant role in all HPV-associated cancers. Recombinant antibodies against specific antigens have shown great promise for the therapy of infectious diseases and cancer.

Xanthones, A Promising Anti-Inflammatory Scaffold
Inflammation is the body’s self-protective response to multiple stimulus, from external harmful substances to internal danger signals released after trauma or cell dysfunction. Many diseases are considered to be related to inflammation, such as cancer, metabolic disorders, aging, and neurodegenerative diseases.  Xanthones, a unique scaffold with a 9H-Xanthen-9-one core structure, widely exist in natural sources. Till now, over 250 xanthones were isolated and identified in plants from the families Gentianaceae and Hypericaceae. Many xanthones have been disclosed with anti-inflammatory properties on different models, either in vitro or in vivo.

Effect of Probiotics on Glucose Metabolism and Homeostasis
The maintenance of a healthy status depends on the coexistence between the host organism and the microbiota. Early studies have already focused on the nutritional properties of probiotics, which may also contribute to the structural changes in the gut microbiota, thereby affecting host metabolism and homeostasis. Maintaining homeostasis in the body is therefore crucial and is reflected at all levels, including that of glucose, a simple sugar molecule that is an essential fuel for normal cellular function. Despite numerous clinical studies that have shown the effect of various probiotics on glucose and its homeostasis, knowledge about the exact function of their mechanism is still scarce.

Anticancer Nanotherapeutics in Clinical Trials
The ultimate goal of nanomedicine has always been the generation of translational technologies that can ameliorate current therapies. Cancer disease represented the primary target of nanotechnology applied to medicine, since its clinical management is characterized by very toxic therapeutics. In this effort, nanomedicine showed the potential to improve the targeting of different drugs by improving their pharmacokinetics properties and to provide the means to generate new concepts of treatments based on physical treatments and biologics.

Bluetongue Virus Vector Vaccines
In this work, we show a deep revision of the viral vector vaccines that have been developed to counteract bluetongue virus (BTV), an arthropod-borne disease that whips domestic and wild ruminants. We analyzed the main advantages and disadvantages of every of them, as well as the immunological features and efficacy that these candidates provided in both murine models and natural hosts.

Multiple Intertwined Processes in MDD
Major depressive disorder (MDD) is a heterogeneous disease that affects one out of five individuals in their lifetime and is the leading cause of disability worldwide. The symptoms of MDD are associated with structural and neurochemical deficits in the corticolimbic brain regions. The behavioral symptoms of depression are extensive, covering emotional, motivational, cognitive, and physiological domains, and include anhedonia, aberrant reward-associated perception, and memory alterations. Presently, MDD is considered a multifactorial disease with various causes and triggers such as genetic susceptibility, stress, and other pathological processes such as inflammation.

Immunological Methods of Common Intestinal Protozoa
Intestinal protozoan infection is a persistent public health problem affecting the populations of developing countries in tropical and subtropical regions. The diagnosis of intestinal protozoa remains a challenge especially in developing countries due to a shortage of laboratory facilities, limited health funding, and the remoteness of communities. Despite still being widely used, conventional diagnoses using microscopy and staining methods pose important limitations, particularly due to their low sensitivities and specificities. The selection of diagnostic methods needs to be carefully considered based on the objective of examination, availability of resources, and the expected parasite to be found. Immunodiagnostic tests are generally inexpensive, user-friendly, and enable fast-obtained results. Antibody and antigen detection tests, such as indirect hemagglutination (IHA), indirect immunofluorescence (IIF), enzyme-linked immunosorbent assay (ELISA), direct fluorescent antibody (DFA), rapid enzyme immune assay (EIA), immunochromatographic test (ICT), or latex agglutination, are commercially available via several different platforms. The combination of antibody and fecal antigen detection assays is more sensitive and specific than microscopy for the diagnosis of several intestinal protozoan infections.

Clinical Aspects of HIV Associated Neurocognitive Impairment
Neurocognitive impairment (NCI) associated with HIV infection of the brain impacts a large proportion of people with HIV (PWH) regardless of antiretroviral therapy (ART). While the number of people with HIV (PWH) and severe NCI has dropped considerably with the introduction of antiretroviral therapy (ART), the sole use of ART is not sufficient to prevent or arrest NCI in many PWH. As the HIV field continues to investigate cure strategies, adjunctive therapies are greatly needed. HIV imaging, cerebrospinal fluid, and pathological studies point to the presence of continual inflammation, and the presence of HIV RNA, DNA, and proteins in the brain despite ART.

Non-alcoholic Fatty Liver Disease Pathogenesis and Oxidative Stress
Non-alcoholic fatty liver disease (NAFLD) is a challenging disease caused by multiple factors, which may partly explain why it still remains an orphan of adequate therapies. It highlights the interaction between oxidative stress (OS) and disturbed lipid metabolism. Several reactive oxygen species generators, including those produced in the gastrointestinal tract, contribute to the lipotoxic hepatic (and extrahepatic) damage by fatty acids and a great variety of their biologically active metabolites in a “multiple parallel-hit model”. This leads to inflammation and fibrogenesis and contributes to NAFLD progression. The alterations of the oxidant/antioxidant balance affect also metabolism-related organelles, leading to lipid peroxidation, mitochondrial dysfunction, and endoplasmic reticulum stress. This OS-induced damage is at least partially counteracted by the physiological antioxidant response. Therefore, modulation of this defense system emerges as an interesting target to prevent NAFLD development and progression. For instance, probiotics, prebiotics, diet, and fecal microbiota transplantation represent new therapeutic approaches targeting the gut microbiota dysbiosis. The OS and its counter-regulation are under the influence of individual genetic and epigenetic factors as well.

Coronary Microvascular Dysfunction
Coronary microvascular dysfunction (CMD) is defined as the clinical syndrome of angina, electrocardiographic ischemic changes in the absence of obstructive CAD. The pathophysiological basis is impaired microvascular vasodilatation, leading to inadequate increase in blood flow to match myocardial oxygen needs (previously referred to in the literature as “cardiac syndrome X”).
