Described herein are single-domain antibodies that might serve as alternatives to conventional monoclonal antibodies for either the detection or treatment of Venezuelan equine encephalitis virus (VEEV).

The present invention provides a new antibody against ECSA type Chikungunya virus, WA type Chikungunya virus, and Asian type Chikungunya virus or an antigen-binding fragment of the antibody. The antibody against Chikungunya virus or the antigen-binding fragment of the antibody of the present invention includes a heavy chain variable region or a heavy chain (1), (2), or (3) and a light chain variable region or a light chain (4).

Described herein are nucleic acids encoding single-domain antibodies that might serve as alternatives to conventional monoclonal antibodies for either the detection or treatment of Chikungunya Virus (CHIKV).

A vaccine composition for prophylaxis and treatment of Chikungunya virus infections is disclosed which is capable of conferring immunity against any genotypic variants of the Chikungunya virus. More particularly the invention discloses particular nucleotide sequences and their translated proteins thereof, which may be expressed as Virus Like Particles which for use as a vaccine antigens against Chikungunya virus infections. The compositions disclosed in this invention are also protective against any genotypic variants of the Chikungunya virus which may be propagated by any suitable vector of the disease including Aedis albopictus and Aedis aegypti.

The invention relates to a vaccine comprising live attenuated recombinant alphavirus comprising mutated capsid protein. The invention also relates to a method of preventing a subject from contracting an alphaviral infection that would otherwise produce clinical signs of disease. In an embodiment the mutated capsid protein is Chikungunya virus (CHIKV) capsid protein having a mutated nucleolar localisation signal/sequence (NoLS), preferably the mutant NLS 101/95.

Proteases of Group IV (+)ssRNA viruses were found to act on a human sequences in addition to the viral sequences. The identity of the cleavable human sequences is disclosed. Detection of these sequences can act as a diagnostic of infection. It is contemplated that these findings could be employed to facilitate post-translational silencing at the level of protein (e.g., removal of existing proteins), thus serving as a protein analog to CRISPR/Cas9 and RNAi/RISC, and further to enable sequence-specific silencing of host functions without the modification of the host genome.

Disclosed herein are recombinant baculoviruses suitable for detecting the presence of arthropod-borne viruses in a biological sample of a test subject. The information derived from the detection may also be used to render a diagnosis on whether the test subject is infected with the arthropod-borne viruses or not, so that proper course of treatment may be assigned to the subject.

The present disclosure is directed to antibodies binding to and neutralizing Chikungunya virus (CHIKV) and methods for use thereof.

Described herein are nucleic acids encoding single-domain antibodies that might serve as alternatives to conventional monoclonal antibodies for either the detection or treatment of Chikungunya Virus (CHIKV).

The present invention relates to a protein receptacle capable of receiving several exogenous polyamino acid sequences, concomitantly, for expression in various systems and for different uses. The present invention relates to polynucleotides capable of generating the aforementioned protein receptacle. The present invention also relates to vector and expression cassette comprising the aforementioned polynucleotide. The present invention further relates to the cell comprising the aforementioned expression vector or cassette. The present invention further relates to a method for producing said protein receptacle and for pathogen identification or disease diagnosis in vitro. The present invention further relates to the use of said protein receptacle and kit comprising said protein receptacle for diagnostic purposes or as vaccine compositions.
