Numerous mysteries of cell and molecular biology have been resolved through extensive research into intracellular processes, which has also resulted in the development of innovative technologies for the treatment of infectious and non-infectious diseases. Some of the deadliest diseases, accounting for a staggering number of deaths, have been caused by viruses. Conventional antiviral therapies have been unable to achieve a feat in combating viral infections. As a result, the healthcare system has come under tremendous pressure globally. Therefore, there is an urgent need to discover and develop newer therapeutic approaches against viruses. One such innovative approach that has recently garnered attention in the research world and can be exploited for developing antiviral therapeutic strategies is the PROteolysis TArgeting Chimeras (PROTAC) technology, in which heterobifunctional compounds are employed for the selective degradation of target proteins by the intracellular protein degradation machinery. This review covers the most recent advancements in PROTAC technology, its diversity and mode of action, and how it can be applied to open up new possibilities for creating cutting-edge antiviral treatments and vaccines.

Introduction. Brucellosis, a globally distributed zoonotic disease, is caused by the Gram-negative bacteria known as Brucella. Humans acquire infection through direct contact with the blood, urine and placenta of animals, inhalation of dust or aerosols at infected animal farms, and raw milk and meat intake. This study aimed to assess the prevalence of brucellosis in dairy farmers in and around the Aligarh region of North India, to document various clinical signs and symptoms in Brucella-positive individuals, and to create awareness in dairy farmers concerning brucellosis and ways to prevent it. Methods. This was an observational study that included 125 dairy farmers in and around the Aligarh region. Serum samples were taken from this high-risk group after obtaining informed consent. Further, a pre-designed proforma was used to collect information about their knowledge, attitude and practices (KAP) concerning brucellosis and assess the risk factors for the disease. The Rose Bengal test (RBT), serum agglutination test (SAT) and enzyme-linked immunosorbent assay (ELISA) were performed to detect the seroprevalence of brucellosis. Result. Brucella infection was diagnosed in 64 (51.20 %) cases by indirect ELISA (IgM+IgG), 41 (32.8 %) by RBT and 4 (3.2 %) by SAT. Significant clustering of patients was seen in the 20–55 years age group. The most common symptoms in ELISA IgM-positive patients were joint pain (16.07 %), fatigue (14.28 %), anorexia (12.50 %), weight loss (8.92 %), malaise (5.35 %), undulant fever (3.57 %), night sweats (3.57 %) and headache (1.78 %). The findings of this study indicate that ELISA (IgM+IgG) exhibits great sensitivity as compared to SAT and RBT. KAP was very poor among dairy farmers. Conclusion. In India, Brucella is a frequent but severely underreported illness. ELISA is the most sensitive serological test for diagnosing brucellosis. No potential vaccine has yet been introduced for humans against brucellosis. Thus, it is necessary to impart awareness and sensitize high-risk groups concerning brucellosis.

Brucellosis is a common zoonotic infection in India, caused by a facultative intracellular bacterium, Gram-negative coccobacillus, and frequently presents with nonspecific symptoms. This study aimed to assess serum cytokine levels (IL-6, IL-10, IFN-γ, and IL-2) by ELISA and to correlate them with inflammatory markers (ESR and CRP) in patients with suspected brucellosis presenting with rheumatoid arthritis-like manifestations and polyarthralgia. This study included 111 patients, comprising 72 brucellosis-positive arthritis patients and 39 brucellosis-negative arthritis patients as controls. In this study, we investigated the variation in levels of four cytokines (IL-2, IL-6, IL-10 and IFN-γ) among brucellosis-positive and brucellosis-negative arthritis patients and their relationship with clinical parameters. The mean serum levels of IL-2 and IL-10 were numerically higher in brucellosis-positive arthritis patients compared to controls; however, these differences were not statistically significant (p > 0.05). Similarly, no statistically significant differences were observed for IL-6 and IFN-γ between the groups. Inflammatory markers such as ESR and CRP were elevated in brucellosis-positive patients, although these differences did not reach statistical significance. These findings indicate variability in cytokine and inflammatory marker levels between groups. The observed associations with raw dairy consumption, contact with unvaccinated livestock, and direct animal exposure highlight the need for early diagnosis, effective livestock immunisation programs, and strengthened One Health-based public health interventions to reduce disease burden.

Brucellosis, a prevalent zoonotic disease in India, causes nonspecific symptoms. Humans contract it via infected animals or by consuming unpasteurized dairy products. This study evaluates the effectiveness of ELISA, Rose Bengal Plate Test (RBPT), and SAT in diagnosing brucellosis from clinical samples. A prospective study was conducted involving 218 patients with unknown fever, arthritis, and neurological symptoms. A detailed history was collected using a pre-designed questionnaire. This study aims to evaluate the clinical diagnostic efficacy of widely used serological assays for human brucellosis, focusing on their sensitivity, specificity, and applicability in clinical settings. Out of 218 clinical samples from suspected brucellosis patients, 129 tested positive for Brucella by either of the serological tests. Male:Female ratio was 1.04:1, and 60% of the patients had a clear history of exposure to cows, buffalo, and goats. ELISA IgG showed the highest positivity rates, identifying 64 (49.6%) cases; ELISA IgM detected 43 (33.3%) cases; the Serum Agglutination Test (SAT) identified 30 (23.2%) cases; RBPT detected 33 (25.5%) cases, and only 14 (10.8%) cases tested positive for ELISA IgG + ELISA IgM. The sensitivities of the ELISA IgG, ELISA IgM, RBPT, SAT, and ELISA IgG + ELISA IgM detection were 69.57%, 46.74%, 35.87%, 32.61%, and 15.22%, respectively, while the specificities were 100%, 100%, 75.40%, 84.92%, and 100%, respectively. ELISA can be used to diagnose human brucellosis reliably and is more sensitive than the SAT and RBPT.
